While trade credit may be used as a substitute for bank loans, we find empirical evidence that listed firms do use bank debt and trade credit as two complementary sources of financing in line with recent theoretical papers (e.g. Biais & Gollier, 1997) and evidence found in other empirical works (e.g. Alphonse, Ducret, & Séverin, 2006). By using a sample of 263 publicly-listed companies from 2006, our findings empirically support that trade credit may be used as (i) a sign of the firm’s quality, and (ii) a way of facilitating access to bank debt as trade credit seems to be a substitute for bank debt.

While trade credit may be used as a substitute for bank loans, we find empirical evidence that listed firms do use bank debt and trade credit as two complementary sources of financing in line with recent theoretical papers (e.g. Biais & Gollier, 1997) and evidence found in other empirical works (e.g. Alphonse, Ducret, & Séverin, 2006). By using a sample of 263 publicly-listed companies from 2006, our findings empirically support that trade credit may be used as (i) a sign of the firms quality, and (ii) a way of facilitating access to bank debt as trade credit seems to be a substitute for bank debt.
Key words: trade credit; public-listed companies; sources of financing; debt.
Trade credit is credit extended by suppliers to buyers, particularly during sales negotiations. Schwartz (1974) reports that trade credit is a complement to bank debt and capital market debt. It diminishes the efficiency of an aggregate monetary control, but on the other hand it mitigates discriminatory effects caused by a restrictive monetary policy, which tends to affect mainly small and medium sized enterprises [SME]. Because of this credit constraint, trade credit is viewed as a financial source of greater importance in countries where financial institutions and capital markets are not fully developed. It does not mean, however, that credit extension (or trade credit) is not relevant in countries with well-developed financial institutions such as the US or Germany. Trade credit is also viewed as an important source of financing for SME, since these firms normally have less access to sources of financing (and are also more affected by restrictive monetary policies). However, trade credit is much used by large firms. In our sample, for example, trade credit use represents around 8% of total debt, or 1/3 of firms financing (excluding corporate debt).
Despite the relevance of trade credit to Brazilian firms, there is no literature about this source of financing using Brazilian data. This study aims to fill this gap. Another innovation introduced by the present study is the focus on Brazilian-listed firms. It is reasonable to expect, therefore, that they have at least the same access to bank loans as private firms. In addition, public listed firms have access to public debt while private firms do not. Nevertheless, the complex procedures for accessing these other sources of financing, the proportionally larger financing needs of public firms and their need to diversify their financing suggest that trade credit may be just as (or almost as) useful for public, large firms as it is for smaller ones.
This study investigates trade credit from the viewpoint of both supplier and buyer based on a sample of Brazilian public firms data. We test the hypothesis of Alphonse, Ducret and Séverin (2006) who argue that credit rationed firms would use trade credit as complementary and alternative source of financing, while firms not facing credit rationing would use it only as an alternative source. The analysis of trade credit supply (the supplier viewpoint) focuses on firms access to credit.
The remainder of this paper is organized as follows. The literature review and hypotheses are presented in Second Section, data description in Third Section and the empirical results and the discussion of results in Fourth Section 4. Fifth Section concludes.
Firms justify supplying trade credit on the basis that, in the absence of such financing, clients who do not have access to credit from financial institutions will not buy their products (Nadiri, 1969). Emery (1984) argues that trade credit provision boosts sales, representing a strategy to reduce firms inventories without price cuts. In this sense, this strategy would avoid costs associated with price reduction and preserve the firms discretionary pricing ability, as pointed out by Petersen and Rajan (1997). An instrument that facilitates this practice is the trade bill, which can be discounted in advance.
Another relevant aspect of trade credit is that it plays a role as a product guarantee when a suppliers reputation is not well known, since clients can observe the quality of products before effectively paying for them (Smith, 1987; Long, Malitz, & Ravid, 1993).
Wilner (2000) additionally argues that, for a supplier that relies on a specific customer, it may be in the suppliers long term interests to grant trade credit to this customer even if the supplier is suffering temporary financial distress. In this sense, the author verified that large buyers faced with credit restraints may use their position (as a large costumer) to obtain trade credit from their suppliers.
Although these reasons justify the interest of non-financial firms in extending trade credit, it is still interesting to ask why they do so in the presence of financial firms specializing in selling credit. The answer is directly related to risk mitigation by non-financial firms in relation to banks. According to Petersen and Rajan (1997), the explanation is mostly related to informational advantages that suppliers experience, compared to banks, due to their business relationship with their clients (The suppliers visits to their clients may provide useful hints about inventories, employee redundancy, clients complaints and other problems that the buyer may eventually face).
First, suppliers may obtain information about their customers in the natural course of business, hence in a more timely and less costly way than banks. As Cook (1997) points out, this can be explained by the fact that suppliers visit their customers on a regular basis: in such visits, suppliers representatives (salespeople, commercial managers) get in touch with buyers employees and representatives of other firms, obtaining information about their relationship with the buyer. Another facilitating factor is that suppliers and buyers frequently belong to related industries, which makes it easy for the suppliers to have a good assessment of their customers market conditions. Moreover, Petersen and Rajan (1997) point out that the frequency and volume of purchases provide a relevant signal about the customers situation.
The business relationship also provides the suppliers with a monitoring advantage. Mian and Simth (1992) state that, faced with a likely default, the supplier can cut futures sales. This attitude can be harmful and even trigger the firms shutdown, especially if there are few alternative suppliers of that input. On the other hand, retaliation from financial institutions does not have as immediate an effect as the suppliers actions. Knowing that suppliers retaliation can lead to their shutdown, buyers have an extra incentive to avoid defaulting on trade credit. Furthermore, Buckart and Ellingsen (2004) argue that goods are more difficult to divert than cash, that is, suppliers can overcome moral hazard easier than banks.
The last advantage mentioned by Petersen and Rajan (1997) has to do with the nature of collateral assets. In case of default, lenders can seize the buyers inventory of goods: however, given the nature of their activities, such assets are less valuable to banks than to suppliers (see also Frank & Maksimovic, 2004 and Longhofer & Santos, 2003). All the advantages of non-financial firms are related to risk mitigation, since these firms can reduce informational asymmetry.
Finally, it is important to explain why firms use trade credit even if it is considered more costly than other forms of credit. There are two main reasons for the interest in its use: (1) trade credit is an alternative source of financing, especially when firms are credit constrained and (2) it is viewed as a sign of good quality of firms, making it easier for them to access bank loans.
Burkart and Ellingsens (2004) model predicts that, in the case of wealthy firms, the use of trade credit has a negative relationship to wealth. Moreover, according to these authors, the least wealthy firms use bank loans and trade credit up to their limit. Cunninghan (2004) empirically verifies Burkart and Ellingsens model (2004). By defining wealth as net income before tax, she found that, for medium-wealth firms, as the limit of bank credit increases, trade credit is less used; and for low-wealth firms, they are directly proportional, which suggests that this type of firm exhausts both limits of bank credit and trade credit.
Petersen and Rajan (1997) found that credit constrained firms use more trade credit, while firms with more access to credit from financial institutions extend more credit to their customers; these results were further corroborated by Biais and Gollier (1997), who also suggest that trade credit can mitigate information asymmetry problems. As explained in the previous section, suppliers have advantage by obtaining information about their buyers in comparison to banks, and hence access to trade credit would work as a sign of the firms good quality, facilitating their access to bank loans. The results of Cook (1997) support this rationale for a country with less developed financial institutions (Russia).
Alphonse et al. (2006) verify this signaling role of trade credit, using data for the US and simultaneous equations (due to the endogeneity problem between bank debt and trade credit). They argue that firms with good relationships with banks would use trade credit only as a substitute source of financing (substitution hypothesis), while credit rationed firms would use it as both, a substitute and complementary source of financing, but at different times. These authors suggest that, credit constrained firms would first use trade credit as complementary source of financing (complementary hypothesis). Banks would consider this information and become more willing to lend to these firms (reputation hypothesis). Hence, these firms would later use trade credit and bank loans as substitute sources (substitution hypothesis).
Hypotheses, Data and Methodology
In order to investigate trade credit from the point of view of both suppliers and customers, this study has been structured into two parts. The first aims to test hypotheses 1, 2 and 3 (described below), which are related to the trade credit use (viewpoint of the customer) and its relation to bank debt. These hypotheses were tested by Alphonse et al. (2006) for SME and are tested in this paper on publicly-listed companies. The second part is composed of hypothesis 4, which are related to trade credit offer (viewpoint of the supplier).
Hypothesis 1: Substitution Hypothesis. Trade credit is an optional source of financing to a bank loan.
Biais and Gollier (1997) state that since trade credit carries information owned by the supplier about its customer, it should mitigate the informational asymmetry between firms and banks. Following this rationale, trade credit would play a signaling role, facilitating the firms access to bank credit for credit rationed firms. In this sense, trade credit would be an optional source of financing for both classes of firms (credit rationed and non-rationed).
In spite of the fact that public firms have their information disclosed (balance sheets, financial statements and other types of information), suppliers have access to superior information, even before they are published. Therefore, we expect that the use of trade credit can favor access to bank loans also for public firms and the accounts payable/total assets indicator is negatively related to total debt/total assets. In order to test trade credit usage, we use the model of Alphonse et al. (2006).
Hypothesis 2: Complementary Hypothesis. Trade credit is a complementary source of financing to bank debt for credit rationed firms.
According to the informational and strategic advantages mentioned above, suppliers could be interested in granting credit even to credit rationed firms. In such a case, the firms accounts payable is expected to have a positive relationship with bank debt.
Hypothesis 3: Reputation Hypothesis. Credit rationed firms that use more trade credit should have easier access to bank debt than those that use less trade credit.
According to the reputation hypothesis, it is expected that the coefficient of total debt is negative and significant for both classes of firms (first equation) and accounts payable is positive and significant only for firms in worse financial health (second equation).
The variable used as a proxy for credit constraint by firms is the bankruptcy prediction score adjusted by Sanvicente and Minardi (1998) for Brazilian firms. Table 1 summarizes hypotheses 1 to 3.
Hypothesis 4: the greater the access to financial sources, the larger the trade credit granted, since the firm is not an indispensable supplier.
Petersen and Rajan (1997), based on a sample of small firms data, found that the easier their access to credit, the more willing they were to supply trade credit. Public firms have access to both bank loans and public debt. Moreover, since they have to disclose their financial statements, they may be considered more transparent than private firms, which facilitates their access to bank loans. Hence, one can expect that public firms have more access to financing sources than small and medium sized enterprises. We therefore expect that aggregate indebtedness would not be as relevant to public firms increasing ability to grant credit than it is to private firms. Furthermore, larger firms tend to be less dependent on their suppliers than SME and for this reason they grant less concessions to their buyers (Wilner, 2000). Based on this rationale, we expect the level of total indebtedness not to be relevant, or even to have a negative relationship with trade credit supply in the case of public firms.
Diamond (1991) states that firms that issue corporate bonds have better reputations than others. Therefore, we expect that such a reputation would amplify the effect of non-dependence, hence bonds to total assets ratio is expected to be more significant than both other loans to total assets and total debt to total assets ratios.
Estimation Method and Variables Description
Analysis of Trade Credit Us
A simultaneous equations model is applied to capture key features concerning the two-way relationship between trade credit and bank debt. There are two equations (Equations 1 and 2) in this system, one related to the use of trade credit, and one related to the use of bank debt by firms.
The first equation attempts to explain cross sectional variations in the use of trade credit by firms as measured by the accounts payable over total assets ratio. According to the substitution hypothesis, this ratio should be inversely related to the amount of debt defined as total loans divided by total assets.
This equation also includes variables related to the transaction use of trade credit. These variables are the ratio of current assets over total assets, a measurement of the sale growth and the (log of) total income. We expect these variables to be positively related to the amount of trade credit use. We also control for ownership, industry and age of the company.
used for testing hypotheses 1 and 3.
used for testing hypotheses 2 and 3.
used for testing hypothesis 4.
In order to test hypotheses 1 to 4, we use a number of proxies to provide empirical evidence of trade credit either as a substitution of bank loan or a complement of bank loan. Tables 2 and 3 summarize the major control variables and their related hypotheses for trade credit use and supply respectively. The variables are described below.
Based on Alphonse et al. (2006), we use the ratio of accounts payable/total assets (ACPAY) as a proxy for trade credit. Access to other forms of credit are represented by bank debt to total assets (BANK) and total debt to total assets (TDEBT). According to the substitution hypothesis, the signal of the coefficient for the total debt to total assets ratio is expected to be negative. The complementary hypothesis predicts that the coefficient for the ratio accounts payable/total assets should be positive.
Ferris (1981) argues that uncertainty of delivery time augments inventory needs for goods and money, which contribute toward increasing the variation in payments and revenues. This rationale is related to the transaction theory of trade credit use. The variables related to this theory are current assets to total assets (CURR) and sales growth between 2005 and 2006 (GROWTH). These variables are directly related to working capital, as well as accounts payable; therefore, one can expect a positive relationship between them. The other variable used is the log of total income (INCOME).
A proxy for industry (IND_1 and IND_2) was included to control for nature of product effects, as pointed out by Giannetti, Burkart and Ellingsen (2007). Both variables are binary; IND_1 represents commodity firms whereas IND_2 represents service firms.
Following Alphonse et al. (2006), the ratio of earnings before tax to total assets (PROFIT) was used as proxy for retained earnings (these authors arguee that this may not be the best measure for retaining earnings; however, it works sufficiently well as a proxy for this variable). According to the pecking order theory, the greater the firms retained earnings, the lower its dependence on external finance (Myers, 1984). Also based on their work, we use the firms age as a representative of the degree of informational asymmetry and of the firms opacity, such as the amount of retaining earnings, financial resources needs and other issues. Hence, a prediction about the relationship between age and accounts payable would be problematic. The measure used was the log of the firms ages (AGE) and the square of the log of the firms ages (SQRAGE).
Like firms age, firms size can be a proxy for some firms characteristics, for example: more transparency (Berger & Udell, 1998), more creditworthiness (Petersen & Rajan, 1997) or fewer financing obstacles (Beck, Demirgüç-Kunt, Laeven, & Maksimovic, 2006). Therefore, it is difficult to predict the sign of log of total assets (SIZE), the variable used as a proxy for firms size, in both analyses. Depreciable assets (DEPR) play a collateral role. When firms creditworthiness can be observed by lenders, low-quality borrowers have to pledge collateral to obtain loans, while high-quality borrowers do not (Boot, Thakort, & Udell, 1991).
Two dummy variables are included as control variables due to the informational asymmetry (Akerlof, 1970) and consequent signaling effects (Spence, 1973) regarding firms quality/creditworthiness. DLEASE takes the value of 1 if the firm uses capital lease and zero otherwise, whereas DSTOCK assumes a value of 1 if the firm benefits from loans from stockholders and zero owtherwise.
The variable GROWTH, related to the transaction theory, is expected to have the same signal as in the first equation (positive), as a stronger growth would demand more working capital, implying an increase in funding needs. The ownership share of the principal owner (OWNER) was included as a proxy for differences in financing patterns (Holmes & Zimmer, 1994).
In order to investigate the reputation hypothesis, the sample was divided by their financial health, and the two equations analysed jointly. The relation of total debt (TDEBT) is expected to be negative for both classes of firms, while the relation between accounts payable (ACPAY) and bank debt would be positive and significant for credit constrained firms and non-significant for firms in good financial health. This corroborates the rationale that in a first stage of credit rationing, firms use trade credit to substitute bank loans; at a later stage, banks would become willing to grant credit to firms that have had access to trade credit.
Analysis of Trade Credit Supply
The analysis of trade credit supply is based on the model of Petersen and Rajan (1997), and some of the variables were redefined accordingly. We use the ratio accounts receivable/total assets (ACREC) as a proxy for trade credit supply. The log of book value of total assets was used to measure firms size (SIZE). The firms age (AGE) has the same definition (log of (1+firm age)). Petersen and Rajan (1997) assert that both size and age of firms indicates their creditworthiness, hence they would be positively related to trade credit supply.
The ratio of gross profit to sales (GR_PROFIT) indicates the incentive that a firm has to sell. Since trade credit is supposed to increase sales, we expect that the greater the gross profit, the greater the incentive the firm has to invest in actions that increase sales. For this reason, gross profit should have a positive relationship with accounts receivable. Sales growth (GROWTH) has the same definition as in the previous section and it should have a negative relationship with accounts receivable, since firms growth may affect working capital management and therefore cause a decline in firms ability to supply trade credit.
TOTAL DEBT is the ratio of total debt to total assets. BONDS is the volume of corporate bonds. LOANS is defined as the difference between total debt ratio and bonds ratio. As previously explained, larger firms are less dependent on their suppliers and thus they would grant fewer concessions to their buyers. Therefore, contrary to small enterprises, debt ratios are expected to be negative, or at least not significant in the case of public firms. We assume that a better reputation of firms that issue public debt intensifies this effect of non-dependence and for this reason bonds ratio coefficient should be more significant than the other debt ratios. Table 3 summarizes control variables and their expected signs and related hypotheses.
Data and Summary Statistics
The sample consists of 263 nonfinancial public firms. The dataset includes annual information from 2006, as provided by Economática® and the website of the Securities and Exchange Commission of Brazil (Comissão de Valores Mobiliários [CVM]). The former was used to obtain financial data (from consolidated balance sheets and financial statements) and industry classification. The latter provided financing data, available in the Notes to the Financial Statements and the foundation year of firms (used to calculate firm age).
The difficulties in obtaining information on bank loans and foundation year imposed some constraints on the sample, causing differences in the number of observations among the equations. Firms are not obligated to report their financing source; therefore, this led to a reduction in the number of observations used in the second equation, where the ratio of bank loans to total debt appears as the dependent variable.
In order to control for the nature of the good effect, the firms in the sample were split according to a simple classification: commodities, services and others1 1 Although simpler than the classification used by Giannetti et al. (2007), this categorization accounts for the main distinctions between firms; there was no single dominant category within the others group, which suggests that an additional group would not be necessary. . Table 4 shows the distribution of firms in the sample according to the industry for the two equations.
Table 5 presents descriptive statistics. Panel A shows financial data of the sample used to analyze trade credit use, while Panel B shows the same data of the sample used to analyze trade credit offer. The differences in total sample between panel A and panel B are due to unavailable data of some variables in each analysis, thus eliminating firms from one sample and not from the other.
Both groups of firms that offer and use less trade credit present high standard deviation, which denotes high variation in data, i.e. they seem not to follow a specific pattern of size (total assets and equity), profitability (net revenue, earnings before interest and taxes (EBIT) and net income), debt and working capital. This evidence, along with the analysis of the mean, shows that both groups seem to present similar characteristics (standard deviations and means). In spite of the median values demonstrating some differences (for instance, total assets in panel B is almost twice the total assets in panel A), the median values compared to mean values demonstrate that these differences are not so ample as they seem to be. The comparison between mean and median also shows that half of the sample presents much lower financial-economic data than the other half. It turns out to be evident by the great difference between mean and median values. Both groups of firms that offer and use more trade credit portray lower standard deviations. Moreover, such groups had greater differences in relation to the means when compared to the other group from the same panel.
Accounts receivable and accounts payable are part of current assets and current liabilities respectively. This means that they are related to working capital. High variation in working capital, in its turn, may denote difficulties in its management and it is expected that firms with high variation in this measure offer less trade credit. On the other hand, one can expect firms with high variation in working capital to use more trade credit, even though that has not been confirmed by the descriptive analysis.
Firms that offer more trade credit have on average lower total assets, equity, EBIT, net income, total debt, and working capital, which is consistent with the rationale that smaller firms have to make greater efforts to sell.
Table 6 reports indirect least squares regression applied to a simultaneous equation system. This method is applied when there is weak endogeneity and it allows the use of different groups of variables in a simultaneous equation system (Vince, 2000). In order to test the endogeneity, predicted and residual values are estimated from the first regression (equation 1) and included in the second regression. The coefficient of residuals was significant at level 1%, which indicates that there is endogeneity between trade credit and bank debt.
We verified the presence of heteroskedasticity, identified by the Breusch-Pagan / Cook-Weisberg test, at level 1% (chi-square was 62.19 for the first equation and 11.90 for the second equation, in trade credit use analysis; and in the analysis of trade credit offer, the chi-square was 144.58). For this reason, the procedure of White was employed in all regressions in order to obtain consistent standard errors.
The first equation seeks to investigate the substitution hypothesis. The ratio accounts payable to total assets presents a significantly negative relationship with the ratio of total debt to total assets, confirming the complementary hypothesis for public firms.
Almost all other results corroborate the findings of Alphonse et al. (2006). Among the variables related to trade credit transaction use, the log of total income and the current assets to total assets ratio are significantly and positively related to trade credit, while sales growth does not present a significant coefficient. Size, proxy for firm opacity (the larger the firm the less opaque it is) presents a negative relationship with trade credit, consistent with the statement that suppliers have superior information about their buyers.
Unlike the results obtained by Alphonse et al. (2006), whereas the ratio earnings before taxes to total assets was significant, the ownership share of principal owner was not. The first ratio captures some aspects of the retained earnings implied process. According to the pecking order theory, a firm prefers to use its own resources to fund its projects before searching for external financing. This implies that the more retained earnings a firm has, the lower its dependence on external funding. Therefore, the negative relationship between accounts payable and earnings before taxes corroborates the pecking order theory. The second ratio might be connected to different financing possibilities just between small firms that are growth and non-growth oriented. Public firms are owned by many shareholders, which can have other firms. Therefore the ownershipshare of the principal owner was not expected to be significant. Age also presents no significant coefficient.
The second equation intends to examine the complementary hypothesis, which states that bank debt and trade credit act as complementary financing sources. The significantly positive relationship between accounts payable (proxy for trade credit) and bank debt ratify the complementary hypothesis to public firms.
Unlike the studies using small firms data (for instance, Biais & Gollier, 1997; Alphonse et al. 2006), size was significantly negative when related to bank debt. One possible reason is that the need for financing is proportional to the firms size, and bank loans would not satisfy this large financing demand. Moreover, large firms can have access to cheaper financing sources. Therefore, the larger the firm, the lower the bank debt to total debt ratio. Another different result is the negative relationship between depreciable assets and bank debt. Depreciable assets are more likely to be financed by long term financing, which would be the case of other sources of financing, especially of corporate bonds. The dummies for leasing (if the firm uses lease capital) and stockholder loans (if the firm benefits from loans from stockholders) do not present significant coefficients.
On the whole, these findings for public firms confirm the study by Alphonse et al. (2006), except for some peculiarities of large firms. They ratify the substitution and complementary hypotheses to this type of firm.
In order to test the reputation hypothesis, the sample was split into two parts, according to the median of a score created by Sanvicente and Minardi (1998) to predict bankruptcy. These results are presented in Table 7. Panel 1 reports the regression using firms whose score is below the median and panel 2, the regression of those whose score is above.
According to the substitution hypothesis, the negative relationship between total debt and accounts payble is valid for both groups of firms. Therefore, the significant results for both classes of firms corroborate the substitution hypothesis and the findings of Alphonse et al. (2006).
According to Biais and Gollier (1997), trade credit is a result of credit rationing and a signal that facilitates access to bank debt. Based on this statement, Alphonse et al. (2006) affirm that trade credit does not play an important role when firms have a long banking relationship (reputation hypothesis) and therefore the complementary hypothesis should only be confirmed in case of firms with less access to bank loans. It implies that the accounts payable coefficient should only be significant for firms with worse financial health. Our results confirm the reputation hypothesis. Therefore, despite public firms being less opaque than SME, trade credit is supposed to make access to bank loans also for public firms facing credit constraints easier. This is explained by the fact that suppliers have access to important information about their customers before they become public. Another relevant result is the significance of the dummy proxy for stockholder loans use (Panel 1), i.e., stockholder loans also facilitate access to bank loans when firms are credit constrained.
Comparing Tables 6 and 7, we can verify that current assets are relevant for both classes of firms in obtaining trade credit. On the other hand, the significance of gross profit and size is explained by firms with greater financial health; although these factors have low sensitivity to accounts payable. Furthermore, the significance of profit is explained by firms with worse financial health. This is consistent with the findings of Evans (1998) and Wilner (2000), who say that dependent suppliers extend more credit when the buyer is in financial distress.
The analisys of trade credit use shows that it can be as (or almost as) useful for public firms as for SME in a country with a financial system that is not fully developed. Therefore, trade credit use can act as a complementary or substitute source of financing, as well as a good sign of a firms quality, facilitating the firms access to financing.
Table 8 shows the OLS regression results. Its objective was to investigate the access to credit and trade credit offer and, additionally, provide some evidence concerning the behavior of excelent reputation firms in granting credit extension to their customers.
The findings related to indebtedness of univariate analyses persisted after being controlled by other variables. Unlike small firms, the more indebted the less the public firm supplies credit. As explained above, this result may be related to the fact that larger firms are less dependent on their buyers, which means they would not need to invest in suppliers in the way that small firms do. As a result, they use loans to invest in other projects. Another explanation is that the customers of publicly-listed firms may have access to other forms of financing. Furthermore, Diamond (1991) found that corporate bonds are issued only by firms with a greater reputation. This is mostly explained by their characteristic of allowing less monitoring and by the fact that public issues usually involve large amounts of capital. We argue that this greater reputation may augment firms market power, decreasing their dependence on their customers. For this reason, when total debt is divided into corporate bonds and other loans, the former have a negative relationship with stronger and significant trade credit coefficient.
This paper investigates the use of trade credit by either financing their clients as well as supplier financing by Brazilian public firms. The rationale presented by Alphonse et al. (2006) provides the basis for the analysis of trade credit usage; the empirical tests of their hypothesis using Brazilian public firms data confirm the hypotheses of substitution and complementariness, that is, trade credit represents both a substitute (for all firms classes) and complementary (for credit rationed firms) source of financing in relation to bank loans, increasing the possibilities of financing for large firms. After spliting the sample into firms with poorer and better financial health, the substitution hypothesis was verified for both classes of firms, while the complementary hypothesis was ratified only for less creditworthy firms. The results provide empirical evidence to support the reputation hypothesis, i.e., trade credit seems to signal a firms good quality, facilitating access to bank loans. Despite public firms being more transparent than small (and private) firms, suppliers have access to relevant information about their buyers even before they become public. Therefore, trade credit can also facilitate access to credit for public firms.
Additionally, we provide empirical evidence about trade credit supply. Our results reveal that, in the case of public firms, an increase in indebtedness leads the firm to supply less trade credit to its clients. One possible explanation is that, unlike small firms, public firms are usually less dependent on their suppliers, therefore, they make fewer concessions to their clients (Frank & Maksimovic, 2004). Another possible explanation is that their clients may have access to sources of financing other than trade credit. When the debt is split into corporate bonds and other loans, this result is more significant for corporate bonds, which indicates that a firms good reputation intensifies the effect of low dependence on buyers. This type of loan is related to a firms reputation which, linked to less dependence of large firms, may be related to an increase in the firms market power, and for this reason these firms would make fewer concessions to their customers than the others.
The main contribution of this paper is the verification that of trade credit use and its relevance for large firms in Brazil, witnessed in the sample of publicly-listed companies, i.e., not only SME, but large Brazilian firms have the disadvantage of a lack of bank loans. We suggest, for future reseach, the use of a sample of SME and large firms in order to compare the use of trade credit between these types of firms.
