Inflation-unemployment tradeoff and regional labor market data

We estimate a linear and a piecewise linear Phillips curve model with regional labor market data for West German and Neue L?nder. Employing regional observations allows us to country difference the data. This eliminates, under the assumption of homogeneous L?nder, supply shocks and changes in the formation of expectations as possible identification failures. With seemingly unrelated regressions we find a flat Phillips curve in the Neue L?nder. For the West German L?nder a piecewise linear model with a higher inflation-unemployment tradeoff for the regime of low unemployment rates fits the data very well. The results hold true if we control for endogeneity of the unemployment rate. With a kinked but upward sloping aggregate supply curve there seems to be room for stabilization policies, at least in the range of aggregate demand shifts that our data covers.

International Banking and Liquidity Allocation

This paper explores the comparative advantage of multinational banking over cross-border financial services in terms of capitalizing on a global access to funding sources. We argue that this advantage depends on the benefit and the cost of multinational banks’ intimacy with local markets. The benefit is that it allows multinational banks to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a bank relies to allocate liquidity across countries. We analyze the conditions under which multinational banking is then likely to arise and show that capital requirements have an effect as they influence the degree of inefficiency in internal capital markets for alternative organization structures differently.     

Limiting efficiency of OLS vs. GLS when regressors are fractionally integrated

We show that previous results on the asymptotic efficiency of OLS vs. GLS in the context of trending data carry over to regressors of the fractionally integrated type.     

A Note on Efficiency Wage Theory and Principal–Agent Theory

Why are principal–agent models used in some circumstances and efficiency wage models in others? In this note, it is argued that efficiency wages provide incentives based on an evaluation of the agent's input, while the incentives analysed in principal–agent models rely on the agent's output. The choice between the two incentive schemes depends on the probability that the agent is caught shirking. Moreover, we demonstrate that a combination of input‐ and output‐related elements provides stronger incentives than payment schemes based on merely one of these elements. However, the combination requires a more complex labour contract involving an increased cost of writing the contract. The interaction between this transaction cost and a hiring cost is analysed.     

Incentives and Selection in Promotion Contests: Is It Possible to Kill Two Birds with One Stone?

This paper investigates whether a designer can improve both the incentive provision and the selection performance of a promotion contest by making the competition more (or less) dynamic. A comparison of static (one‐stage) and dynamic (two‐stage) contests reveals that this is not the case. A structural change that improves the performance in one dimension leads to a deterioration in the other dimension. This suggests that modifications of the contest structure are an alternative to strategic handicaps. A key advantage of structural handicaps over participant‐specific ones is that the implementation of the former does not require prior identification of worker types.

Financing Decisions along a Firm’s Life‐cycle: Debt as a Commitment Device

We analyse the life‐cycle patterns of a firm’s financing decisions and their interaction with future growth and development decisions. We derive different financing sequences which we link to existing empirical research as well as derive new testable hypotheses regarding differences in firms’ financing decisions to project, firm, market and country characteristics. We provide a rationale for the importance of (external) start‐up debt financing as observed in recent empirical studies. Furthermore, we argue that equity financing at both development stages is more likely for closely‐held firms and in countries in which entrepreneurs face high stigmatisation costs.     

Dynamisierung kapitalgedeckter Altersvorsorge

On the basis of the annual reports of all the life insurance companies covered by the Federal Financial Supervisory Authority (BaFin), the adjustment of payments over the time period 2002 to 2012 is analysed for Germany. The analysis unveils large differences in the adjustment rates of the insurers, not only among companies but also over time. Therefore a steady income stream, a constant income level and the reliability of payments are not ensured for policy holders. In general, the adjustments lead to increasing inequality of income during retirement and rising income heterogeneity in private households. Even worse, these forms of income provision during retirement are not able to compensate for the reduction in the benefit level of statutory old age provision in Germany.     

Divergent regional development, factor mobility, and nontraded goods

Using an endogenous growth model with learning-by-doing effects in the production of a traded good, we derive divergent regional-growth paths in a two-region-three-good setting. A nontraded-goods sector using a mobile as well as an immobile factor of production provides the possibility of a steady-state equilibrium with a dispersed distribution of mobile workers. The paper investigates regional specialization, trade, and migration patterns in the steady-state equilibrium as well as in the transition process towards the steady-state. The long-run production and trade patterns of the regions are determined by history-dependent processes.
