CEO Overconfidence,REIT Investment Activity and Performance

This is the first article to study the effects of overconfidence on trading activity and performance in real estate. The article looks at Real Estate Investment Trusts (REITs), as their investments and divestments can be identified with precision. We look at the effect of CEO overconfidence on investment activity and separately investigate property acquisitions and dispositions. We find that REITs with overconfident CEOs tend to invest more; these REITs acquire more assets and are less likely to sell assets than their counterparts if they have enough discretionary cash. Valuable private information is not the main driver for CEOs to be net buyers of company shares: the shares of their companies perform relatively weakly. In addition, we find that overconfident managers have lower property investment performance measured by net operating income and gain on sale of real estate.     

Structural problems of the next few years

The Federal Republic of Germany will be facing in the next few years changes in its economic structure which, if not in their extent, in their effect on the employment situation will be without parallel in the post-war period. After fifteen years of nearly uninterrupted full employment, it is reasonable to expect in the medium term an over-all rate of unemployment of the order of 2–3 p.c. (0.5–0.7 mn).     

The need for re-organising the UN-system

The leadership, as well as the organisational structure and the working routine of the UN in as far as they are mainly concerned with development political questions and international economic cooperation are increasingly coming under cross-fire from critics in all parts of the world. A case in point was the recent interpellation by the group of CDU/CSU members in the German Federal Parliament. The subject of this parliamentary inquiry was the re-organisation of the economic and social sectors of the UN. In the following article the member of Parliament, Dr Volkmar Köhler, explains why the interpellation was tabled. His explanation is followed by the publication of item number 10 of the inquiry and the reply by the Minister of State in the Foreign Office, Hans-Jürgen Wischnewski.     

Harmonization of company taxation systems

The author of the following article gives a survey of the different corporation tax systems and rates in the individual EC-member countries, explains the need for a harmonization of direct company taxation within the Community, and discusses the Commission’s recent proposal as compared with other possible approaches.     

Ruin probabilities and aggregrate claims distributions for shot noise Cox processes

We consider a risk process R _t where the claim arrival process is a superposition of a homogeneous Poisson process and a Cox process with a Poisson shot noise intensity process, capturing the effect of sudden increases of the claim intensity due to external events. The distribution of the aggregate claim size is investigated under these assumptions. For both light-tailed and heavy-tailed claim size distributions, asymptotic estimates for infinite-time and finite-time ruin probabilities are derived. Moreover, we discuss an extension of the model to an adaptive premium rule that is dynamically adjusted according to past claims experience.     

Outsourcing,Occupational Restructuring,and Employee Well‐Being: Is There a Silver Lining?

This study examines the relationship between outsourcing and various aspects of employee well‐being by devoting special attention to the role of occupational restructuring as a conveying mechanism. Using linked employer–employee data, we find that offshoring involves job destruction, especially when the destination is a low‐wage country. In such circumstances, staying employees’ job satisfaction is reduced. However, the relationship between outsourcing and employee well‐being is not entirely negative. Our evidence also shows that offshoring to high‐wage countries stimulates the vertical mobility of employees in affected firms in a manner that improves perceived well‐being, particularly in terms of better prospects for promotion.     

A problem-adjusted genetic algorithm for flexibility design

Many present markets for goods and services have highly volatile demand due to short life cycles and strong competition in saturated environments. Determination of capacity levels is difficult because capacities often need to be set long before demand realizes. In order to avoid capacity-demand mismatches, operations managers employ mix-flexible resources which allow them to shift excess demands to unused capacities. The Flexibility Design Problem (FDP) models the decision on the optimal configuration of a flexible (manufacturing) network. FDP is a difficult stochastic optimization problem, for which traditional exact approaches are not able to solve but the smallest instances in reasonable time. We develop a Flexibility Design Genetic Algorithm (FGA) that exploits qualitative insights into the structure of good solutions, such as the well-established chaining principle, to enhance its performance. FGA is compared to a commercial solver, a simple GA, and a Simulated Annealing local search on instances of up to 15 demand types and resources. Experimental evidence shows that the proposed approach outperforms the competing methods with respect to both computing time and solution quality.     

Transaction cost economics in global sourcing: Assessing regional differences and implications for performance

This paper addresses two gaps in current research on transaction cost economics (TCE): first, the fundamental claim suggesting that firms that align their governance structure to transactions according to TCE perform better than those that do not, and second, the application of TCE to global sourcing transactions. A research model is presented and evaluated using a set of 150 relationships between Swiss buyers and foreign suppliers. The findings suggest that there are significant differences in how transactions and governance structures are aligned with varying performance and with suppliers from Western Europe as compared to suppliers from other regions.     

Sustainable agricultural intensification: the role of cardamom agroforestry in the East Usambaras,Tanzania

The East Usambaras in Tanzania are a tropical biodiversity hotspot where current agricultural management practices pose threats to forest conservation and development objectives. Promoting sustainable agricultural intensification (SAI) would improve long-term productivity and reduce pressure on forest reserves. The study objective was to identify household-level characteristics that influence adoption of improved management practices, specifically soil replenishment practices, in order to identify opportunities and constraints to scaling up SAI to landscape level. First, three common farming systems and a fourth agroforestry (AF) model were developed to estimate the relative profitability of incorporating fallow, manure, and non-timber forest product activities. Next, household surveys were conducted and a logistic regression analysis was used to measure the influence of socioeconomic characteristics, physical and financial assets, tenure security, and plot-specific attributes on adoption of soil replenishment practices that were specified in the model. Findings showed that the AF model was financially competitive but raises opportunity costs to labour when compared to common systems. Marital status, household size, remittances, credit access, and tenure security significantly influenced adoption of fallow and applying organic inputs. Significant plot-specific attributes included perceived fertility and distance from the homestead. Policies to scale up SAI should consider these factors and emphasize improving markets for AF species and extension services.
