Trade Credit Model : A Time Elasticity Approach

We develop a theoretical model to explain the impact of market power in the product market and financial constraints on trade credit extension. Our model is based on a rational profit maximizing firm operating with a certain level of market power represented by the price elasticity of its product and with customers presenting a certain degree of financial constraint which reflects in their trade credit term-sensitivity of demand. Besides showing the detailed deduction of this model using a non-linear programming approach (Kuhn-Tucker) we show the trade-offs that firms face to increase their profit by selling on credit and compare its implications to the trade credit literature. We further confirm our findings empirically using Compustat quarterly data for 8,602 US firms drawn from 2004 to 2010
