Indicators, Green Accounting and Environment Statistics— Information Requirements for Sustainable Development

Since the "Earth Summit" in Rio de Janeiro 1992 the term "sustainable development" determines the third and current phase of environmental policy. A precise and commonly accepted definition of sustainable development (s.d.) is still missing. There are, nevertheless, some elements in the philosophy of sustainable development which–even if they are still vague–could be used as guidelines for a framework of "green" accounting and sustainability indicators. Based on theoretical considerations, the German Federal Statistical Office has developed a framework for an Environmental Economic Accounting System. The objective is to add meaningful modules to the traditional System of National Accounts which are designed to quantify the external (environmental) effects of economic activities. The framework could already be realised and published to an extent that is relevant for actual policy making in Germany.     

The Term Structure of Interest Rates in a Small Open Economy: A Stochastic Analysis

This article employs a rational expectations IS-LM model with price adjustment to study the effect of domestic monetary and fiscal policy and world interest rate disturbances on the real and nominal small open economy term structure of interest rates. The impact of both temporary and permanent shocks are investigated. Notable results include the fact that monetary expansions lead to positive yield curves, while the implications of fiscal expansions and increases in the world interest rate depend crucially on the duration of the shock.     

On the Hybrid Nature of REITs

The consensus that emerges from the current research on the linkage between securitized and direct investment in real estate is that direct (private) real estate returns play a relatively minor role in the real estate investment trust (REIT) return generating process. However, this result may at least partially be due to the coarseness of the measures of direct real estate returns or the relatively short return horizons used in previous studies. This study takes a different and unique perspective. Unlike earlier studies we do not use aggregated, average appraisal based returns on direct real estate investment. Instead, we use the MIT TBI indexes, which are transaction based price indexes, available both on the aggregate and sub-index levels. We find that the relation between REIT and direct real estate returns appears to be stronger at longer horizons. More specifically, using a cointegration framework, we find robust evidence that REITs and the underlying real estate are related and that they share a long run equilibrium. Interestingly, we find that both REITs and direct real estate returns adjust towards this long run relationship. When we examine property type level data we find similar results.     

Heavily regulated,but promising prospects: Entry in the German Express Coach Market

Domestic express coach services in Germany have long been heavily restricted by regulation, although offerings comparable to countries like, for example, Great Britain or Sweden bear substantial opportunities for competition, the environment, and mobility. In this paper, we motivate market entry in the German express coach market for local public and integrated transport companies by high profitability rates in other countries and the availability of bus facilities and skills. This is followed by the evaluation of supply and demand. Supply is represented by an analysis of external and internal costs showing that express coaches have significant cost advantages that are intensified by the possible internalization of external costs. Demand is represented by a survey of customers that is evaluated with a conjoint analysis. Our results suggest a market share for express coach services in Germany of at least 5.3%.
