It is well known that if there are mild sector-specific externalities, then the steady state of the standard two-sector real business cycle model can become locally indeterminate and endogenous business cycles can arise. We show that this result is not robust to the introduction of standard...

In this paper, we analyze the importance of the frequency of decision making for macroeconomic dynamics. We explain how the frequency of decision making (period length) and the unit of time measurement (calibration frequency) differ and study the implications of this difference for macroeconomic...

This Paper explores the local stability properties of the steady state in the two-sector neo-classical growth model with sector–specific externalities. We show analytically that capital adjustment costs of any size preclude local indeterminacy nearby the steady state for every empirically...

Using a game theoretical model on firms' simultaneous investments in product and process innovation, we deduct and empirically test hypotheses on the optimal R&D portfolio, investment, performance, and dynamic efficiency of R&D for acquisitions and in independently competing firms. We use...

We evaluate the social welfare loss (WL) that arises in an oligopolistic industry under technological competition and product differentiation. The main novelty of our approach concerns the decomposition of the WL into `dynamic' losses (from too little cost reduction and an inappropriate number...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

How should monetary policy respond to changes in financial conditions? In this paper we consider a simple model where firms are subject to idyosincratic shocks which may force them to default on their debt. Firms' assets and liabilities are denominated in nominal terms and predetermined when...

This paper discusses three aspects of stabilization and international integration: the real wage; inflation; and the real effective exchange rate. Using empirical evidence on inflation and the real effective exchange rate, we evaluate the gradualist option represented by the Hungarian reforms....

The paper analyses, along the transition path and in steady state, the optimal stabilization policy in an economy in which growth is driven by learning by doing. If future benefits of learning by doing are not fully internalized by workers the optimal fiscal policy is to tax labour during...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...
