A standard time‐inconsistency model of monetary policy, extended to include a time‐varying natural rate of unemployment, implies cointegration between the inflation rate and the unemployment rate. An application of the model to data for the EMU countries does not yield strong evidence of cointegration. In addition, the sign of the estimated coefficient of cointegration is not in line with a sign restriction imposed by the time‐inconsistency model.  相似文献

Using unique data, we address the issue of price formation in a limit order market. A standard volume–volatility relation is documented with the number of trades acting as the important component of volume. The main contribution of the paper is to identify strong evidence that volume, volatility, and the volume–volatility relation are negatively related to the order book slope. These results are robust to the inclusion of several liquidity measures. A significant empirical relationship between the order book slope and the coefficient of variation in earnings forecasts by financial analysts suggests that the slope is proxying for disagreement among investors. Hence, our results support models where investor heterogeneity intensifies the volume–volatility relation.  相似文献

This paper evaluates business cycle effects of asymmetric cross‐country mortgage market developments in a monetary union. By employing a two‐country New Keynesian DSGE model with collateral constraints tied to housing values, we show that a change in institutional characteristics of mortgage markets, such as the loan‐to‐value (LTV) ratio, is an important driver of asymmetric developments in housing markets and economic activity. Our analysis suggests that the home country where credit standards are lax booms, while the rest of European Monetary Union faces a negative output gap. Overall welfare is lower if LTV ratios are higher.  相似文献

Norm-violating behavior is characterized by clear social norms which prescribe the non-occurrence of that behavior. From the theoretical framework of Allport it is derived that specifically norm-conformation is consistent, while violating norms is expected to be inconsistent and more circumstantial. This is in contrast to test-theoretic approaches of delinquent behavior that assume that various norm-violating responses form a consistent answer pattern that is scalable and reliable. In this study we study the inter-correlations, scalability and reliability of norm-violating responses and their relation with the reduction of zero observations. In concordance with Allport’s view it is expected that different norm-violating self-report items have limited interrelatedness and are limited in scalability and reliability in the norm-violating sub-population. The NLSY98 self-report data show that a large majority of respondents (69 %) conform systematically to all ten different norms, while only nine percent admits more than two different violations. The results show that in subsamples of norm-violating respondents, the correlations between items become closer to zero, dependent on the amount of zero reduction. Furthermore, both Loevinger’s H coefficient of scalability and scale reliability become unsatisfactorily low, when 35 % or more strict norm-conforming subjects are removed.  相似文献

Organic agriculture was Europeanized through two EU regulations which defined and provided financial support for it. In transposing these regulations, member states have had to deal with political aspects of the conflict between mainstream and organic agriculture. A comparison of 13 new (including former socialist states) and old member states illustrates that the level of conflict had an impact only on the level of financial support transposed, while other aspects of transposition were explained by formal institutional preconditions. Low financial support was found in those member states with a high level of conflict or a low value-based level of conflict. Medium financial support was found in one new and one old member state characterized by medium level conflicts. High financial support appeared in three member states characterized by truly low level conflicts in terms of common organic and mainstream agriculture interests.  相似文献

In the Norwegian life insurance company Fram a continuous mortality investigation takes place in connection with the yearly valuation of policies issued with weekly premiums. The investigation gives the aggregate mortality, the unit is the policy and the year of observation is the calendar year. A detailed account of the method used has been given by Fredrik Borch in his paper: “The mortality among industrial insured lives in Norway 1931–1940” in this journal 1943. The most important results of the investigation from the years 1940–1946 are rendered below.  相似文献

This paper analyzes how inequality in Before and After Government income has changed in Germany since reunification using the 1990 through 1992 waves of the German Socio-Economic Panel. A Theil decomposable inequality index is used to measure inequality in Germany and in its eastern and western states. Massive public transfers from west to east have narrowed the east-west income gap, substantially offset the rise in income inequality from private sources, and lowered overall inequality in the western states. The net result of this policy has been a drop in After Government income inequality in Germany between 1990 and 1992.  相似文献
