The objective of our paper is to analyze the prospects for LNG development in the US. In particular, we discuss LNG investment projects with respect to natural gas supply and demand, existing transmission infrastructure, and competing pipeline projects. At the same time potential competition between natural gas and coal in power generation is taken into account. We conclude that in the mid-term, LNG ...

In this paper, we present a detailed and comprehensive complementarity model for computing market equilibrium values in the European natural gas system. Market players include producers and their marketing arms which we call "traders", pipeline and storage operators, marketers, LNG liquefiers, regasifiers, tankers, and three end-use consumption sectors. The economic behavior of producers, traders, ...

We estimate the Sticky Information Phillips Curve model of Mankiw and Reis (2002) using survey expectations of professional forecasters from four major European economies. Our estimates imply that inflation expectations in France, Germany, and the United Kingdom are updated about once a year, while in Italy, about once each 6 months.

Numerous studies proved that people tend to select partners that are similar to them with regard to many social and psychological variables. Even though this effect was also found for personality, results are inconsistent and reveal convergence coefficients ranging from negative over zero- to positive correlations. The present study thus aims to investigate personality congruence between spouses and ...

This paper investigates the link between the optimal level of non-financial firms' liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms alter their liquidity ratio in response to changes in either macroeconomic or idiosyneratic uncertainty. We test this hypothesis using a panel of non-financial US firms drawn from the COMPUSTAT ...

We investigate the effects of regional and industrywide foreign presence and foreign direct investment (FDI) on the export volumes of Ukrainian manufacturing firms using unpublished panel data from 1996-2000. Foreign presence through FDI may have negative competition effects on domestic firms' performance; at the same time, domestic firms' productivity may be increased by technology transfer or training ...

Germany is known to have one of the lowest fertility rates among Western European countries and also relatively low employment rates of mothers with young children. Although these trends have been observed during the last decades, the German public has only recently begun discussing these issues. In order to reverse these trends, the German government recently passed a reform of the parental leave ...

The traditional approach to measuring allocative efficiency exploits input prices, which are rarely known at the firm level. This paper proves allocative efficiency can be measured as a profit-oriented distance to the frontier in a profit-technical efficiency space. This new approach does not require information on input prices. To validate the new approach, we perform a Monte-Carlo experiment providing ...

We evaluate the interaction of inflation and growth forecast errors based on 17 distinct forecasts for the German economy for the period from 1970 to 2004. The forecasts were produced by 14 institutions. Our findings show that, in general, the forecasters did not share a common belief about the shocks driving the economy at the time at which they made their forecasts. We use a standard textbook aggregate-demand/aggregate-supply ...
