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

During the 1980s, rising income inequality in the UK resulted partly from market conditions, and partly from supply-side policies that reduced social security benefits and income supports for low-wage earners. Greater Inequality, plus low levels of investment spending (relative to consumption)hinder the ability of demand management to raise the level of output and employment in the UK economy. Higher income earners have higher import propensities. Consequently, at any stage of the economic cycle, the trade dificit is now larger than it was before 1980. Increases in demand leak into a demand for imports, further reducing the incentive to invest. The paper argues for lower interest rates to encourage investment, and a fiscal policy that redistributes income towards those with lower incomes to solve these problems.  相似文献

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.  相似文献

If the denominational structure of the euro is used in an optimal way, there should be no preferences for certain coins and notes when making cash payments. In Kippers et al. [2003. An empirical study of cash payments. Statistica Neerlandica 57, 484-508] it is documented that the Dutch public did have certain preferences concerning the Dutch guilder in the sense that a few notes and coins were used less often than they should have been. With the advent of the euro, which changed the denominational structure from 1--5 (guilder) to 1-2-5 (euro), it is of interest to examine whether there are any preferences for euro coins and notes. In this paper we use a unique dataset for the Netherlands to empirically examine if the euro range is used in an optimal way. We find that there are no preferences for certain euro denominations.  相似文献

In this introductory paper we introduce the special issue on “Backcasting for Sustainability”. We present briefly a historical background, and position backcasting in the wider context of future studies, in which it can be related to “normative forecasting” and normative scenarios. We reflect on the diversity and variety of backcasting studies and experiments, as presented in the ten papers for this special issue. After summarizing the papers we formulate a future research agenda.  相似文献

An infinite game is approximated by restricting the players to finite subsets of their pure strategy spaces. A strategic approximationof an infinite game is a countable subset of pure strategies with the property that limits of all equilibria of all sequences of approximating games whose finite strategy sets eventually include each member of the countable set must be equilibria of the infinite game. We provide conditions under which infinite games admit strategic approximations.  相似文献

Are celebrity endorsements worthwhile investments in advertising? To answer this question, we analyze a unique sample of 101 announcements made between 1996 and 2008 by firms listed in the USA. Internet is the main medium of communication for these announcements. We employ event study methodology and document statistically insignificant abnormal returns around the announcement dates. This finding is consistent with the notion that the incremental benefits from celebrity endorsements closely match the incremental costs due to such contracts. Further, we investigate if the announcement date return depends on a number of characteristics that are often used in the endorsement literature. As a result, we find that endorsements of technology industry products coincide with significant positive abnormal returns around the announcement dates. Finally, we find weak support for the match-up hypothesis between celebrities and endorsed products.  相似文献

Estimating the cost of liquidity in agricultural futures markets is challenging because bid‐ask spreads are usually not observed. Based on an ability to reflect simulated data from Roll's spread model, we assess the effectiveness of conventional and Bayesian bid‐ask spread estimators under different market conditions. Conventional serial covariance and absolute price change spread estimators appear to be biased. Hasbrouck's Bayesian estimator generates small costs of liquidity whose values depend on the correlation and noise in the data. The absolute value Bayesian estimator is precise and works well under conditions of high levels of noise and correlation usually found in agricultural futures markets. Using data from live cattle (LC) and lean hog (LH) contracts, we find similar patterns of performance that produce economically meaningful cost of liquidity differences.  相似文献
