FROM BOTTOM TO TOP: THE ENTIRE INCOME DISTRIBUTION IN GERMANY, 1992–2003

We analyze the distribution of market income in Germany in the period 1992 to 2003 on the basis of an integrated dataset that encompasses the whole spectrum of the population, from the very poor to the very rich. We find a modest increase of the Gini coefficient, a substantial drop of median income and a remarkable growth of the income share accruing to the economic elite, which we define as the richest 0.001 percent of persons in the population. While the elite mainly obtains its income from business and capital, the income share that it receives in the form of wage income has been increasing. We also show that the dramatic decline of market income in the bottom half of the distribution is very much mitigated by income transfers within private households and by governmental redistribution.     

Simulation model of the polish economy

This paper presents some results of the simulation model of the Polish economy in transition from the planned to market one. The simulation model is nonlinear and dynamic. It consists of 800 balance equations, 40 of which are difference state equations. The basic time unit is one quarter while the calculation horizon spans between three and 10 years. It was calibrated to the 1994–96 statistical data. The model contains the aggregates of production (divided between the state and private sectors and three production branches), households, public sector, banking system, and foreign trade. The simulation attempts to forecast chosen macroeconomic variables resulting from different scenarios. Sets of effective (Pareto-optimal) solutions and effective growth paths of economy were obtained. The simulation results help to better understand the macroeconomic process in the transition period and can be useful for central-level decisionmakers. This work was partially supported by grant No. 1 HO2B 023 09 from Komitet Badan Naukowych (Polish State Committee for Scientific Research).     

Tractable dynamic global games and applications

We present a family of tractable dynamic global games and its applications. Agents privately learn about a fixed fundamental, and repeatedly adjust their investments while facing frictions. The game exhibits many externalities: payoffs may depend on the volume of investment, on its volatility, and on its concentration. The solution is driven by an invariance result: aggregate investment is (in a pivotal contingency) invariant to a large family of frictions. We use the invariance result to examine how frictions, including those similar to the Tobin tax, affect equilibrium. We identify conditions under which frictions discourage harmful behavior without compromising investment volume.     

Durkheim's sociology,Simiand's positive political economy and the German historical school

During the nineteenth century, French political economy eluded the historical method. In the light of such context, the way Emile Durkheim and François Simiand interpreted the contribution of the German historical school is worth considering. Following Durkheim's sociological approach, Simiand occupies center stage when it comes to examining how much this historical method has to offer to ‘positive political economy’ considered as an alternative to ‘orthodox political economy’ and to the new conception of economic history which was finding its way through the Annales' school.     

Inequality and growth: What comes from the different inequality measures?

The objective of the paper is to verify if income inequality impedes the growth rates in OECD countries in the period of 1990–2014 and to reveal whether the choice of the income inequality measure determines the sign and the strength of the estimated relationship. We use system GMM to estimate parameters of a dynamic panel growth model. The research indicates that income inequality negatively affects economic growth. We also find evidence that various measures of inequality bring the different scale of consequences for economic growth, with measures that give more weight to the middle part of the distribution being the weakest predictor of GDP growth. Simultaneously, we present the test of weak instruments, which helps to explain these differences.     

The implication of extreme events on policy responses

This paper considers a situation where a real risk exists that requires precautions, but the public mostly experiences the risk through infrequently occurring extreme events; this type of risk includes risk from climate change, international terrorism, natural calamities or financial crises. The analysis shows that if a risk-mitigating policy is based on the perceived riskiness of that risk, it will call for disproportionate responses (compared to what the ‘real’ risk suggests) by either under- or over-investing in risk-reducing policies, depending on the characteristics of the problem, implying significant volatility in the policy response. This type of response provides at least three challenges to society: policy cycles where implementation lags behind the actual change in risk, a lock-in to inefficient technologies and additional costs. Finally, this paper addresses the question of how the above-mentioned challenges can be managed through proper risk communication.     

Manipulation in U.S. REIT Investment Performance Evaluation: Empirical Evidence

We investigate whether Real Estate Investment Trust (REIT) managers actively manipulate performance measures in spite of the strict regulation under the REIT regime. We provide empirical evidence that is consistent with this hypothesis. Specifically, manipulation strategies may rely on the opportunistic use of leverage. However, manipulation does not appear to be uniform across REIT sectors and seems to become more common as the level of competition in the underlying property sector increases. We employ a set of commonly used traditional performance measures and a recently developed manipulation-proof measure (MPPM, Goetzmann et al., Rev Finan Stud 20(5):1503–1546, 2007) to evaluate the performance of 147 REITs from seven different property sectors over the period 1991–2009. Our findings suggest that the existing REIT regulation may fail to mitigate a substantial agency conflict and that investors can benefit from evaluating return information carefully in order to avoid potentially manipulative funds.     

Production functions and distributions of unit factor productivities: Uncovering the link

We derive a reversible “endogenous technology choice transform,” according to which firm-level production functions and distributions of unit factor productivities are two sides of the same coin. The Cobb–Douglas function relates to Pareto distributions, and the CES to Weibull distributions.
