This paper studies corporate risk management in a context with financial constraints and imperfect competition on the product market. We show that the interactions between firms heavily affect their hedging demand. As a general rule, the firms’ hedging demand decreases with the correlation...

Using a dynamic model of a step-by-step innovation race between financially constrained firms, I study how financial constraints affect innovation activity. The novel theoretical results derive from an analysis of the interaction between the incentive effect of competition on innovation and the...

We study an economy where agents are heterogeneous in terms of observable wealth and unobservable talent. Adverse selection forces creditors to ask for collateral. We study the two-way interaction between rationing in the credit market and the wages offered in the labour market. Both pooling and...

It is typically less profitable for an opportunistic borrower to divert inputs than to divert cash. Suppliers, therefore, may lend more liberally than banks. This simple argument is at the core of our contract theoretic model of trade credit in competitive markets. The model implies that trade...

We consider an infinite-horizon inter-generational economy with identical agents differing only in their inherited wealth and with a constant-returns-to-scale technology using capital and labour (called "effort") and displaying a purely idiosyncratic risk. If effort is contractible, full...

This technical Appendix describes the structural model used as part of the Spatial Eco- nomic Research Centre's work for the Northern Way on linkages between the Manchester and Leeds City Regions. A summary of the research, as well as a full report of the findings, can be found on the web-sites...

The Wong-Viner Envelope Theorem on the equality of long-run and short-run marginal costs (LRMC and SRMC) is reformulated for convex but generally nondifferentiable cost functions. The marginal cost can be formalized as the multi-valued subdifferential a.k.a. the subgradient set but, in itself,...

The purpose of our work is to explore contagious financial crises. To this end, we use simplified, thus numerically solvable, versions of our general model [Goodhart, Sunirand and Tsomocos (2003)]. The model incorporates heterogeneous agents, banks and endogenous default, thus allowing various...

We provide an equilibrium multi-asset pricing model with micro-founded systemic risk and heterogeneous investors. Systemic risk arises due to excessive leverage and risk taking induced by free-riding externalities. Global risk-sensitive financial regulations are introduced with a view of...

We use a general equilibrium life-cycle model with incomplete markets and heterogeneous agents to evaluate the macroeconomic and welfare implications of Defined Benefit (DB) versus Defined Contribution (DC) systems, and to investigate the effects of incremental reform within a particular system....
