Johannes Berger Thomas Davoine Philip Schuster Ludwig Strohner 《International Tax and Public Finance》2016,23(6):1160-1184
As life expectancy increases and fertility declines, population aging puts pressure on the financing of welfare states in Europe and other developed countries. Given that immigrant workers are younger than the domestic population, a continuous flow of immigrants reduces the old-age dependency ratio and improves financing. Existing general equilibrium estimates of the public finance contribution of migration, performed with different models, are not comparable across countries and sometimes differ even in sign. We use the same overlapping-generations model with a detailed representation of institutions and labor market activity to provide comparable estimates of the impact of immigration on public finance in four European countries. We find that future projected immigration flows are equivalent to 14.3 % points labor income taxes in Austria, 7.3 points in Germany, 6.2 points in the UK and 1.7 points in Poland in 2060. These differences are due to the projected volume of immigration and institutional setups, among other factors. For comparable volumes of immigration, future flows have largest impact in Germany and smallest in the UK. 相似文献

Business and Marketing Ethics as Professional Ethics. Concepts, Approaches and Typologies 总被引:2,自引:0,他引:2
Johannes Brinkmann 《Journal of Business Ethics》2002,41(1-2):159-177
Marketing ethics is normally marketed as a sub-specialization of business ethics. In this paper, marketing ethics serves as an umbrella term for advertising, PR and sales ethics and as an example of professional ethics. To structure the paper, four approaches are distinguished, with a focus on typical professional conflicts, codes, roles or climates respectively. Since the moral climate approachis more inclusive than the other approaches, the last part of the paper deals mainly with moral climates, within the above-mentioned marketing sub-professions. 相似文献

The formula given by McLennan [The mean number of real roots of a multihomogeneous system of polynomial equations, Amer. J. Math. 124 (2002) 49–73] is applied to the mean number of Nash equilibria of random two-player normal form games in which the two players have M and N pure strategies respectively. Holding M fixed while N→∞, the expected number of Nash equilibria is approximately . Letting M=N→∞, the expected number of Nash equilibria is , where is a constant, and almost all equilibria have each player assigning positive probability to approximately 31.5915 percent of her pure strategies. 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 examines the relationship between dynamic structural econometric models (SEM) and time series (TS) models. It extends the work of others by suggesting a reconciliation of SEM and TS models based on classical linear parameter restrictions in regression models rather than on time series methods. The paper demonstrates that in a number of common economic contexts there exist sets of plausible restrictions on the stochastic properties of the disturbances and on the dynamic adjustment processes in a SEM such that familiar structural models take on the form of univariate TS models. Consequently, it is argued that TS models should not be arbitrarily dismissed as being devoid of economic content. 相似文献

Summary In this paper we try to clarify whether the use ofBox-Jenkins methods would have improved the forecasting performance in Austria during the recession of 1975. For this purpose we estimate ARIMA models for gross national product, private consumption, investment in plant and equipment, and inventory investment. We then compare the forecasts derived from these models with the results of more convential forecasting techniques. It can not be expected that Box-Jenkins methods predict a business cycle turning point. But, as soon as the recession was under way Box-Jenkins methods were faster in adapting to the new situation than conventional forecasting techniques. We found that the accuracy of Box-Jenkins predictions depends to a large extent on the length of the forecasting horizon. Our results suggest that the forecasting horizon should not exceed one year. All in all, Box-Jenkins methods applied together with the forecasting techniques already in use could further improve the forecasting performance. 相似文献

In this paper we provide detailed evidence on the performance of exporters compared to non-exporters in Austrian manufacturing industries based on firm-level data. The centrepiece of the study is the issue of the export premium, i.e. the size and productivity advantages of exporting firms compared to their purely domestic peers. We present evidence for the existence of sales, labour productivity and wage premia. These results are largely in line with the results found for other European countries. Furthermore we document the existence of large differences in these premia across industries and provide explanations for this finding. Our results are robust with regards to including additional firm control variables such as employment and R&D-related variables though the magnitudes of the export premia become much smaller. We also propose a new interpretation of the export premium estimation with firm fixed effects which we interpret as a result on export switchers. Finally, we employ a probit model to document the importance of sunk export costs for the decision to export. 相似文献

These articles debate the pros and cons of the full income-splitting tax procedure. Ernst Niemeier defends this taxation scheme, because in his opinion it is not aimed at furthering families or children but making sure that a couple does not have to pay more taxes than two singles. He argues that there are constitutional reasons to treat equal incomes equally, which he refers to as “horizontal justice”. Furthermore, he rejects evidence of a negative labour supply effect on the second earner. A team of authors at the DIW find his argumentation not at all convincing. First, they say, determining tax justice or ability to pay is ultimately a political question and cannot be determined by scientists or the courts. Thus, a constitutional determination of marriage taxation on the existing full income-splitting procedure is excessive. Second, the empirical evidence of negative labour supply effects of full income splitting for the second earner can simply not be denied. Niemeier argues why such supply effects cannot exist. 相似文献
