Long, Malitz, and Ravid (1993) proposed a model based on the idea that the major purpose of trade credit is to allow buyers to assess the quality of the firm's products before paying. In this paper, we apply a similar methodology not only using a sample of industrial firms, but also a sample of Belgian wholesale distribution firms. Furthermore, we develop and test two additional hypotheses, based on the observation that industrial and financial groupings play an important role in the Belgian economy. While our results partially confirm the four hypotheses of Long et al., we find evidence that a firm selling to a linked customer extends trade credit for reasons other than assessing product quality. We find that when a firm has a shortage of cash, investment in accounts receivable from linked firms is reduced. An excess of cash does not seem to influence trade credit policy. 0 Most firms have an important amount of cash invested in accounts receivable. Trade credit is also a major source of financing through accounts payable. There have been several sorts of explanations proposed for trade credit. Finance-based models (e.g. Schwartz, 1974) argue that firms able to obtain funds at a low cost will offer trade credit to firms facing higher financing costs. Tax-based models (e.g. Brick and Fung, 1984) see trade credit as arbitraging tax differences between buyers and sellers. Liquiditybased models (e.g. Emery, 1984) see trade credit as a more profitable short-term investment than marketable securities. Operational models (e.g. Emery, 1987) stress its role in smoothing demand. Recently, Scherr (1996) examined optimal limits for trade credit.Recently, Long, Malitz, and Ravid (1993), inspired by Smith (1987), argued that trade credit allows customers to assess product quality before paying.
Similar models have been developed by Lee and Stowe (1993) and Emery and Nayar (1994). The Long et al. model is our starting point. After setting out its main ideas and hypotheses, we test it by using two samples: 393 Belgian industrial firms and 288 Belgian wholesale distribution firms. The results partially confirm the predictions of the model.We then extend the model to take into account other financial connections among firms using trade credit. For the last 150 years, industrial and financial groupings and combines have played an important role in the Belgian economy. Holding companies seem to substitute for poorly developed Belgian capital markets, in order to organize the flows of funds between group members. Trade credit is one dimension in a com...
