In an efficiency wage economy, lump-sum severance pay from which shirkers can be excluded raises employment. However, severance payments are usually related to wages. It is shown that earnings-related, mandated severance pay will have ambiguous employment effects if effort can be varied...

Decisions by firms and individuals on the extent of their tax payments have generally been treated as separate choices. Empirically, a positive relationship between corporate and personal income tax evasion can be observed. The theoretical analysis in this paper shows that a manager's decision...

Models of the new economic geography share a number of common conclusions, but also exhibit notable differences, in particular with respect to the shape of the location pattern and the efficiency of the market equilibrium. This reflects the fact that these models rely heavily on specific...

Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...

"We present a dynamic two-region model with overlapping generations. There are two types of public expenditure, education and infrastructure funding, and governments decide optimally on budget size (tax rate) and its allocation across the two outlays. Productivity of government infrastructure...

Unemployment Insurance Savings Accounts (UISAs) entitle workers to unemployment benefits at the expense of future pension payments. Therefore, such accounts make unemployment less attractive, intensify job search, and raise employment. In the present paper the wage and employment consequences of...

We analyze an oligopolistic market where a domestic and a foreign firm are engaged in a takeover battle for a domestic competitor. Any merger or acquisition (M&A) must be approved by a welfare maximizing domestic competition agency which may or may not be prone to "economic patriotism". A...

Evidently, the benefit-structure of the unemployment insurance has a significant influence on profits and trade union utility. We show for a wage bargaining model that a stronger earnings relationship of unemployment benefits may reduce wages and increase employment. This raises the question as...

We develop a general equilibrium model of international trade with heterogeneous firms, where countries can invest into basic research to improve their technological potential. These research investments tighten firm selection and raise the average productivity of firms in the market, thereby...

We analyze the first data set on consistently defined functional urban areas in Europe and compare the European to the US urban system. City sizes in Europe do not follow a power law: the largest cities are "too small" to follow Zipf's law.
