This paper studies aggregate dynamics in a cobweb model where learning takes place through a selection mechanism, by which more successful firms are replicated at a higher rate. The structure of the model allows to characterize analytically the aggregate dynamics, and to compute the effect on...

Klimaanpassung stellt heute eine Priorität für Entwicklungsländer dar, besonders für die am wenigsten entwickelten Länder. Landwirtschaft ist weltweit ein wichtiger Sektor, aber eine Auseinandersetzung mit dem Thema ist vor allem in den Entwicklungsländern von hoher Bedeutung. Der Sektor...

We develop a simple model of managing a system subject to pollution damage under risk of an abrupt and random jump in the damage coefficient. The model allows the full dynamic characterization of the optimal emission policies under uncertainty. The results, that imply prudent behavior due to...

This paper argues that climate change poses two distinct, if related, sets of challenges for poor rural households: challenges related to the increasing frequency and severity of weather shocks and challenges related to long-term shifts in temperature, rainfall patterns, water availability, and...

Releases of the GDP are subject to revisions over time. This paper examines the predictability of German GDP revisions using forecast rationality tests. Previous studies of German GDP covering data until 1997 finds that revisions of real seasonally adjusted GDP are predictable. This paper uses a...

This paper reviews the adjustments of the feed-in tariff for new solar photovoltaics (PV) installations in Germany. As PV system prices declined rapidly over the last years, the German government implemented automatic mechanisms to adjust the support level for new installations in response to...

A non-linear model is applied where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction. We call the latter a "play" area-analogous to mechanical play and implement an algorithm describing path-dependent play-hysteresis into a regression...

The European Central Bank's monetary policy addresses the euro-area average inflation rate. By setting conditions for the area as a whole it should ensure symmetric price adjustment. Indeed, consumer price inflation rates provide little evidence of asymmetric adjustment during 2009-11. Only...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...

Die Anpassung an die Folgen des Klimawandels ist ein neues politisch-planerisches Handlungsfeld. Aufgrund der Erkenntnisse, dass der Klimawandel nicht mehr zu verhindern ist und die Folgen des Klimawandels eine Vorbereitung der Regionen erfordern, beginnen diese mit Hilfe von Förderprogrammen...

We use data from the Survey of Income and Program Participation covering the period 1989-2006 to investigate the impact that time limits on receipt of Temporary Assistance for Needy Families have on female-headed family outcomes, including welfare use, employment and living arrangements. The...

This discussion paper provides the contextual framework of the cumulative dissertation on “Climate Change and Corporate Innovation Processes” at the Technical University of Dresden. It consists of six already published papers and articles. Because of the present public discussion on climate...

In two experiments we studied the effects of behavioral models on routine deviation decisions in observers. Participants repeatedly chose among four card-deck lotteries together with a human model (confederate, Exp. 1) or a non-human model (computer, Exp. 2) that made correct decisions in the...

The latest round of international negotiations in Copenhagen led to a set of commitments on emission reductions which are unlikely to stabilise global warming below or around 2°C. As a consequence, in the absence of additional ambitious policy measures, adaptation will be needed to address...

Dieses Papier untersucht die Haltung industrieller Arbeitgeber zur Einführung einer staatlichen Arbeitslosenversicherung in Deutschland zur Zeit des Kaiserreichs und der Weimarer Republik. Arbeitgeber lehnten ursprünglich eine staatliche Arbeitslosenversicherung ab, stimmten ihr jedoch am Ende...

By estimating a staggered price model over the period 1980q1-2010q2, this paper documents that, after the euro changeover, Italian retailers have increased the number of price adjustments, which has translated into a higher inflation rate, with a detrimental effect on the competitiveness of the...

This article presents a study of the influences on the factors that shape wage adjustments. The cost of living, comparability with other firms' wages, the fulfilment of collective agreements at sector level, the need to recruit and retain employees, the performance of the organisation, and the...

This paper examines the speed of the occupational adjustment of immigrants using Labour Force Surveys 2004 and 2005 from Statistics Netherlands. The analysis provides new evidence that immigrants start with jobs at the lower levels of skill distribution. Their occupational achievement improves...

The economic impact of the 2007-2009 increases in the federal minimum wage (MW) is analyzed using a sample of quick-service restaurants in Georgia and Alabama. Store-level biweekly payroll records for individual employees are used, allowing us to precisely measure the MW compliance cost for each...
