This paper studies a simple duopoly model of price competition under exchange rate uncertainty with pre-set prices and differentiated goods. Competitors come from different countries and compete in a foreign market. We study the effect of the price setting currency chosen on expected prices,...

This paper examines the effect of using Black and Scholes formula for pricing and hedging options in a discrete time heteroskedastic environment. This is done by a simulation procedure where asset returns are generated from a GARCH (1,1)-t model. In the simulation a hypothetical trader writes an...

The generalised entropy measure is applied to decompose overall income inequality over several years into one part showing inequality of long-run (permanent) income and one part showing variability of single individuals' incomes over time. By comparing these components of inequality for pre- and...

This paper provides an overview of the Swedish social security system and its impact on individual retirement behavior. First, we give some historical facts, as well as a more detailed description of the current situation, of labor market behavior of older persons. Second, we describe the social...

We consider interest rate models where the forward rates are allowed to be driven by a multidimensional Wiener process as well as by a marked point process. Assuming a deterministic volatility structure, and using ideas from systems and control theory, we investigate when the input-output map...

Using detailed micro data from the Indonesian manufacturing sector, we examine the effect on productivity of direct foreign investment. The results suggest that direct foreign investment benefits locally owned establishments. The effect differs between groups of industries. Spillovers from DFI...

In the classical ARCH model of Engle [1982] the conditional variance is a linear function of lagged squared residuals. In this paper I introduce nonlinearity, by adding a term that consists of a constant parameter multiplied by a transition function. Two different transition functions are...

Using detailed micro data from the Indonesian manufacturing sector, we examine whether participation in international trade affects establishments' productivity. Establishments participating in exports or imports have relatively high levels of productivity. Furthermore, the results suggest that...

This paper analyses the effects of non-tariff barriers, in terms of both variable and fixed export costs, on the structure of trade and industry. We find that the relationship between fixed and variable trade costs affects industrial structure and determines whether international trade emerges....

This paper analyzes a finite horizon, sequential move pricing duopoly, restricting attention to Markov-strategies. The solution yields stationary patterns, independent of initial conditions, where the reaction-functions follow cycles of three periods. The market price never settles down, and is...
