We study the effects of German unification on macroeconomic variables in a model with capital accumulation, skill differences and a welfare state. The integration of two economies differing in capital holdings and skill distribution is similar to a mass migration of low-skilled agents holding no...

This Paper is an exercise in dating the euro area business cycle on a monthly basis. We construct several monthly European real GDP series, and then apply the Bry-Boschan (1971) procedure. Using this method we identify four business cycles. Studying further indicators of business activity, we...

This paper examines the business cycle properties of a small set of real US macroeconomic time series using a variety of detrending methods. It is shown: (i) that both quantitatively and qualitatively `stylized facts' of US business cycles vary widely across detrending methods; (ii) that...

Why is there delay in contests? In this Paper we follow and extend the line of reasoning of Carl von Clausewitz to explain delay. For a given contest technology, delay may occur if there is an asymmetry between defense and attack, if the expected change in relative strengths is moderate, and if...

We relate the phenomena of sluggish interregional labour reallocation and in-kind compensation in Russia to 'attachment' strategies of firms: Paying wages in non-monetary forms makes it hard for workers to raise the cash needed for quitting their region in order to find better jobs in more...

Contestants have to choose whether to initiate a contest or war, or whether to remain peaceful for another period. We find that agents wait and initiate the contest once their rival is sufficiently weak to be an easy target.

We analyse the consumption strategy of a dynamically inconsistent individual for goods that provide an immediate benefit and a delayed cost. The agent has incomplete information on the cost inherent to each unit of consumption and partially learns this value anytime he consumes. We show that, by...

Economists often play crucial roles in designing and implementing public policies; thus it is of importance to better understand the values that underlie their decisions. We explore the value hierarchies of economists in four studies: The first two studies examine whether value differences exist...

Using a survey approach, we ask consumers to reveal their preferences over pricing schemes that may differ in terms of the average price of consumption, the amount of price variation, and the probability of being rationed. We find that consumers dislike pricing schemes that vary prices more but...

Several recent studies found that the behaviour of economists was less cooperative than the behaviour of non-economists. Other studies found, however, that economists behaved no differently than other individuals. In this Paper, we study this issue by examining personal value priorities of...
