This dissertation consists of two essays in international macroeconomics. Thefirst essay shows that optimal fiscal and monetary policy is time consistent in astandard small open economy. Further, there exist many maturity structuresof public debt capable of rendering the optimal policy time...

This paper investigates the strategic behavior between countries that have purchasing power on the world market for a certain good. Tariffs and quotas are not equivalent protection instruments in this oligopsonistic market. Policy active importers would be better off by colluding and setting...

Longer horizon returns are modeled by two approaches, which have different impact on skewness and excess kurtosis. The Levy approach, which considers the random variable at longer horizon as the cumulants of i.i.d random variables from shorter horizons, tends to decrease skewness and excess...

In the framework of Knightian uncertainty more precisely in the model introduced by Epstein and Schneider 3 different questions concerning the aspect of time-consistency, in the sense of m-stability or rectangularity, are studied.The first part describes an alternative description of...

We consider long-run behavior of agents assessing risk in terms of dynamic convex risk measures or, equivalently, utility in terms of dynamic variational preferences in an uncertain setting. By virtue of a robust representation, we show that all uncertainty is revealed in the limit and agents...

In this paper we give an alternative characterization for time-consistent sets of measures in a discrete setting. For each measure \mathbb{P} in a time-consistent set \mathcal{P} we get a distinct set of predictable processes which in return decribe the \mathbb{P} uniquely. This implies we get a...

Dramatic changes in the relative prices of goods in international trade have accompanied, and indeed preceded, the global crisis. These changes are reflected in the terms of trade ofindividual countries and in the relative prices of goods within those countries. Asia-Pacific countries are...

We contribute to the task of identifying trends and cycles in energy prices by examining very long series of prices for coal and oil, going back to 1650 in the case of coal and 1859 in the case of oil. We find annual rates of increase in real price of greater than two percent are found for coal...

This paper investigates the welfare costs of business cycles in a heterogeneous agent, overlapping generations economy which is distinguished by idiosyncratic labor market risk. Aggregate variation arises both in terms of aggregate productivity shocks and countercyclical variation in the...
