We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. In a three stage game, firms first decide on the budget allocated to their R&D department, then form research clusters and finally compete in quantities. The second stage cluster formation...

This paper presents a numerical method for the characterization of Markov-perfect equilibria of symmetric differential games exhibiting coexisting stable steady-states. The method relying on the calculation of 'local value functions' through collocation in overlapping parts of the state space,...

The paper explores the causes of China's rising manufacturing exports to the EU after WTO accession. While the European trade policy environment remained largely unchanged in most sectors, a spillover from a change in US trade policies towards China is emphasized. In the proposed model the...

This paper explores how different credit market and banking regulations affect business fluctuations. Capital adequacy and reserve requirements are analysed for their effect on the risk of severe downturns. We develop an agent-based macroeconomic model in which financial contagion is transmitted...

This paper studies fiscal policy behavior with regard to sustainability for the group of the eight eastern new member states (NMS) which joined the European Union (EU) in 2004. Using the approach of Bohn (1995, 1998) the fiscal reaction function is estimated for the years 1995 until 2013....

Do fiscal stabilization policies affect the long-term growth of the economy? If so, are the long-term effects growth-enhancing or growth-reducing? These questions have again become relevant to the political and academic debate since governments have been forced to spend considerable funds for...

This paper examines a dynamic incumbent-entrant framework with stochastic evolution of the (inverse) demand, in which both the optimal timing of the investments and the capacity choices are explicitly considered. We find that the incumbent invests earlier than the entrant and that entry...

Empirical evidence shows that innovative firms are often more constrained in obtaining external funds than less innovative firms. Explanations are based on the uncertain outcome and high costs of R&D effort. When providing credit, the lender assesses the creditworthiness of the borrower. She...

We study an economy with a high degree of financialization in which (non-financial) firms need loans from commercial banks to finance production, service debt, and make long-term investments. Along the business cycle, the economy follows Minskyan dynamics with firms traversing various stages of...

This paper combines horizontal and vertical innovations to build an endogenous growth model that allows for structural change. Older technologies are continuously replaced by newer ones due to creative destruction and new technologies appear as a result of horizontal innovations and as a result...
