This paper proposes a model where heterogeneous firms choose whether to undertake R&D or not. Innovative firms are more productive, have larger investment opportunities and lower own funds for necessary tangible continuation investments than non-innovating firms. As a result, they are...

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these...

We assess some likely consequences of commercial policy in an intertemporal CGE model of an imperfectly competitive, small open economy. Specifically, we combine an overlapping generations model of aggregate savings with capital accumulation by forward-looking investors and production under...

The paper proposes an intertemporal equilibrium model with monopolistic competition and start-up investment with variable capacity to explain the nexus between business formation and medium-run growth. An investment externality is identified that results in under-accumulation of capital in the...

We evaluate potential costs and benefits of Eastern enlargement of the EU. In addressing fiscal costs of enlargement in addition to tariff and non-tariff barriers, we arrive at important conclusions: 1) Overall, extending EU membership to Eastern applicants is more than worth its price to...

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...

A model of start-up finance with double moral hazard is proposed. Entrepreneurs have ideas but lack their own resources as well as commercial experience. Venture capitalists provide start-up finance and managerial support. Both types of agents thus jointly contribute to the firm's success, but...

This Paper discusses the role of public policy towards the venture capital industry. The model emphasises four margins: supply of entrepreneurs due to career choice, entry of venture capital funds and search for investment opportunities, simultaneous entrepreneurial effort and managerial advice...

In recent years, venture capital has increasingly become a factor in the financing of new firms. We examine how the value of mature firms determines the incentives of entrepreneurs to start up new firms and of venture capitalists to finance and advise them. We examine how capital gains taxes as...

To prevent profit shifting by manipulation of transfer prices, tax authorities typically apply the arm's length principle in corporate taxation and use comparable market prices to `correctly' assess the value of intracompany trade and royalty income of multinationals. We develop a model of...
