The role of finance in production and international trade

•We reveal the role of finance in production.•We investigate how finance can affect trade volume.•We explore how finance can affect trade pattern. We introduce finance in a neo-classical general equilibrium model of production and international trade to integrate the core microeconomic theory with the theory of finance. The stock of credit, as past savings, finances employment and the acquisition of machines or capital goods. The availability of finance or international financial flows does not affect production or trade patterns, except for nominal factor prices, in undistorted competitive structures. However, distortions such as unemployment, imperfect credit markets, and factor mobility do affect real outcomes and trade. Our results are consistent with contemporary empirical evidence and have policy implications for financial development and institutional quality. Numerical illustrations provide further insights.
