We study a model of individual wage bargaining between heterogeneous workers and firms, with instantaneous matching, free firm entry, workers’ individual productivities are discovered by firms only after being hired, and it is expensive for firms to hire and fire workers. We show that inefficiencies due to bargaining and externalities in the matching process lead firms to employ too few worker ...

An agent-based model for firms’ dynamics is developed. The model consists of firm agents with identical characteristic parameters and a bank agent. Dynamics of those agents is described by their balance sheets. Each firm tries to maximize its expected profit with possible risks in market. Infinite growth of a firm directed by the “profit maximization” principle is suppressed by a concept of “go...

Credit constraints are more frequent among growth companies with large investment opportunities. For the same reason, profit taxes may harm innovative firms more than standard ones. This paper develops a model of heterogeneous firms where an endogenous share opts for innovation and faces credit constraints in the subsequent expansion phase. We emphasize four results: (i) R&D subsidies not only ...

Economics challenge the specification of discretionary accrual models. Since rent seeking firms pursue differentiated business strategies, firms in the same industry have heterogeneous accrual generating processes. Moreover, Schumpeter’s “creative destruction” forces existing firms to revise their extant business models. We present evidence that such business model shocks are widespread, propag...

Using a dynamic heterogeneous agent industry model we examine the impact of manager remuneration schemes on firms investment decisions and on the evolution of their competitiveness and share values. Whereas an increase in the share-based manager remuneration component is always beneficial to the manager, it is beneficial for shareholders only if such a change in the remuneration scheme is adopt...

We show that after monetary policy announcements, the conditional volatility of stock market returns rises more for firms with stickier prices than for firms with more flexible prices. This differential reaction is economically large as well as strikingly robust to a broad array of checks. These results suggest that menu costs—broadly defined to include physical costs of price adjustment, infor...

This paper investigates firms’ optimal location choices explicitly accounting for the role of inwards and outwards knowledge spillovers in a dynamic Cournot oligopoly with firms that are heterogeneous in their ability to carry out cost-reducing R&D. Firms can either locate in an industrial cluster or in isolation. Technological spillovers are exchanged between the firms in the cluster. It is sh...

Adopting an evolutionary approach, we explain the conjectural variations firms may hold in duopoly. Given conjectures, firms play the market game rationally. Success in the market game determines fitness in the evolutionary game. Based on linear heterogeneous Cournot and Bertrand competition models, we show that the unique conjectures that are evolutionarily stable are consistent in that they a...

This paper explores the concept of knowledge networks in order to disclose how firms are able to increase innovative performance as a result of network structure and network content, which concern how firms connect with network partners (network structure), what the essence of exchange is for firms to acquire knowledge in the network (knowledge heterogeneity), and why firms need to cooperate wi...

Within a horizontal differentiation model and allowing for heterogeneous qualities, we analyze the effects of reference pricing reimbursement on firms' pricing strategies. With this analysis we find inherent incentives for firms' pricing behavior, and consequently we shed some light on the time consistency of such policy. The analysis encompasses different reference price rules: (i) reference p...
