In der vorliegenden Studie werden die sozialpolitischen Reformen in den USA und Kanada während der 1990er Jahren in einer vergleichenden Perspektive analysiert. Dabei wird insbesondere die Rolle steuerpolitischer Instrumentarien in den Reformen thematisiert und der Frage nachgegangen, ob sich hier ein neuer Typ von Wohlfahrtsstaat herausbildet. Im ersten Teil des Papiers wird das in der vergleichenden Wohlfahrtsstaatsforschung etablierte Modell des liberalen Wohlfahrtsstaats skizziert, um vor diesem Hintergrund die Reformen in den USA und Kanada zu untersuchen und zu vergleichen. Anschließend wird in einer breiteren vergleichenden Perspektive die out-put-Leistung der beiden Wohlfahrtsstaaten analysiert. Al normative Kriterien hierbei gilt in erster Linie die Umverteilungsfunktion sozialpolitischer Instrumentarien, hier in erster Linie verstanden als Einkommensumverteilung.
We characterize the response of U.S., German and British stock, bond and foreign exchange markets to real-time U.S. macroeconomic news. Our analysis is based on a unique data set of high-frequency futures returns for each of the markets. We find that news surprises produce conditional mean jumps; hence high-frequency stock, bond and exchange rate dynamics are linked to fundamentals. The details of the linkages are particularly intriguing as regards equity markets. We show that equity markets react differently to the same news depending on the state of the economy, with bad news having a positive impact during expansions and the traditionally-expected negative impact during recessions. We rationalize this by temporal variation in the competing "cash flow" and "discount rate" effects for equity valuation. This finding helps explain the time-varying correlation between stock and bond returns, and the relatively small equity market news effect when averaged across expansions and recessions. Lastly, relying on the pronounced heteroskedasticity in the high-frequency data, we document important contemporaneous linkages across all markets and countries over-and-above the direct news announcement effects.

We develop an estimated model of the U.S. economy in which agents form expectations by continually updating their beliefs regarding the behavior of the economy and monetary policy. We explore the effects of policymakers' misperceptions of the natural rate of unemployment during the late 1960s and 1970s on the formation of expectations and macroeconomic outcomes. We find that the combination of monetary policy directed at tight stabilization of unemployment near its perceived natural rate and large real-time errors in estimates of the natural rate uprooted heretofore quiescent in inflation expectations and destabilized the economy. Had monetary policy reacted less aggressively to perceived unemployment gaps, in inflation expectations would have remained anchored and the stag inflation of the 1970s would have been avoided. Indeed, we find that less activist policies would have been more effective at stabilizing both in inflation and unemployment. We argue that policymakers, learning from the experience of the 1970s, eschewed activist policies in favor of policies that concentrated on the achievement of price stability, contributing to the subsequent improvements in macroeconomic performance of the U.S. economy.
We take a simple time-series approach to modeling and forecasting daily average temperature in U.S. cities, and we inquire systematically as to whether it may prove useful from the vantage point of participants in the weather derivatives market. The answer is, perhaps surprisingly, yes. Time-series modeling reveals conditional mean dynamics, and crucially, strong conditional variance dynamics, in daily average temperature, and it reveals sharp differences between the distribution of temperature and the distribution of temperature surprises. As we argue, it also holds promise for producing the long-horizon predictive densities crucial for pricing weather derivatives, so that additional inquiry into time-series weather forecasting methods will likely prove useful in weather derivatives contexts.
Am Beginn des 21. Jahrhunderts wird der Zustand der US-Demokratie kontrovers diskutiert. Während manche Beobachter eine zu hohe Responsivität des politischen Systems gegenüber den Ansprüchen seiner Bürger entdeckt haben wollen und deshalb von demosclerosis und einer Hyperdemokratie sprechen, in welcher der Volkswille in einen unantastbaren, göttlichen Rang erhoben worden sei, kommen andere zu dem Schluss, dass die Gründerväter im Hinblick auf ihre handlungsanleitende Furcht vor einer »Tyrannei der Mehrheit« ganze Arbeit geleistet und ein nahezu unüberwindbares System von Vetopositionen geschaffen hätten, das Partikularinteressen strukturell bevorzuge und deshalb nur in Ausnahmesituationen die Mehrheitspräferenzen der Bürger in Politik umsetze. Kurzum: Die Furcht der Federalists vor einer »Mehrheitstyrannei« habe einer »Minderheitstyrannei« Tür und Tor geöffnet. Der Artikel versucht die Vereinigten Staaten in diesem Spannungsbogen zu verorten. Ziel ist es, die Qualität der amerikanischen Demokratie am Beginn des 21. Jahrhunderts zu problematisieren. Dabei werden auch die Entwicklungen nach dem 11. September berücksichtigt.
