Abstract We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas, and Stengos (2003) . However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the number of citations of articles published in the previous 10 years. This allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year, because of new entrants.  相似文献

We study the stationarity of consumption-income ratio (APC) in OECD countries. To that end, we use three different bootstrapping techniques to construct the 90% confidence intervals. The results show that the APC is non-stationary in most of the countries.  相似文献

While earlier empirical studies found a negative saving effect of old-age dependency rates without considering longevity, recent studies have found that longevity has a positive effect on growth without considering old-age dependency rates. In this paper, we first justify the related yet independent roles of longevity and old-age dependency rates in determining saving and growth by using a growth model that encompasses both neoclassical and endogenous growth models as special cases. Using panel data from a recent World Bank data set, we then find that the longevity effect is positive and the dependency effect is negative in savings and investment regressions. The estimates indicate that the differences in the demographic variables across countries or over time can well explain the differences in aggregate savings rates. We also find that both population age structure and life expectancy are important contributing factors to growth.  相似文献

This paper investigates the effects of interest rate and foreign exchange rate changes on Turkish banks' stock returns using the OLS and GARCH estimation models. The results suggest that interest rate and exchange rate changes have a negative and significant impact on the conditional bank stock return. Also, bank stock return sensitivities are found to be stronger for market return than interest rates and exchange rates, implying that market return plays an important role in determining the dynamics of conditional return of bank stocks. The results further indicate that interest rate and exchange rate volatility are the major determinants of the conditional bank stock return volatility.  相似文献

Abstract.  Using a model of interdependent tax choices, and accounting for equalization entitlements and general transfers, this paper estimates – making use of a spatial econometric framework – corporate income tax-setting functions for all Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.  相似文献

In this paper we examine a number of issues that arise in investigating labor force dynamics using the Spanish Labor Force Survey (EPA). These issues are by no means specific to the Spanish case and apply to most European-style labor force surveys. Our main conclusions may be summarized as follows. First, survey nonresponse cannot be neglected. Second, the EPA tends to underestimate employment and participation of high-educated young people, and to overestimate those of the low-educated elderly. Finally, we find little evidence that attrition causes important selection biases in estimating quarterly transition probabilities.  相似文献

We model the aid allocation process as a rent-seeking contest between two countries and investigate the effects of differing allocation rules on recipients' behavior in a simple framework. We investigate the aid allocation mechanism design that attempts to increase the governance quality of potential recipient countries: the potential recipients spend costly resources improving governance, while the donor country allocates the fund based on their governance quality. The paper compares two mechanisms: one uses a simple winner-takes-all tournament to award the entire available purse to the country with the best governance; while under the other aid is distributed among countries in proportion to their governance qualities. The paper shows the second mechanism outperforms the first only if competing countries are sufficiently asymmetric. Moreover, the recipient who is most effective in governance – and stands to benefit the most from development assistance – has interests opposite to those of the donor. In addition, the paper shows that if the donor country allocates the fund based on both governance and the levels of poverty, it may result in a poverty trap: the leaders of potential recipient countries deliberately allocate funds away from the poorest so as not to better their position in order to receive more aid.  相似文献

This paper studies the effect of poor governance quality on foreign direct investment in Russia. Using a survey of businesses across forty administrative districts, we find that higher frequency of using illegal payments and higher pressure from regulatory agencies, enforcement authorities, and criminals, negatively affect foreign direct investment. Our identification strategy builds on the exogenous cross-regional variation in worker strikes during 1895–1914, the period before the October Revolution. We find that moving from the average to the top governance quality across Russian regions more than doubles the FDI stock.  相似文献

The price of houses and its evolution in recent years is one of the issues that citizens and, of course, political and economic authorities are worried about. In most of the developed countries the mean price (per square meter) of houses in an area is estimated by a simple average of single prices from a sample of houses that does not take into account the spatial correlation among the prices. As an alternative to this classic procedure, in this paper we propose a linear estimator of the mean price of houses, using the kriging estimator, which has been specially designed for the case of spatially correlated data in a given domain. This estimator is the best unbiased linear one and provides a more realistic estimate of the mean price of houses in the urban area we are interested in. Obviously, the modelling of the variogram function is a central point in the global estimation process.  相似文献

Viewpoint: Replication in economics   总被引:2,自引:0,他引:2  
Abstract.  This examination of the role and potential for replication in economics points out the paucity of both pure replication – checking on others' published papers using their data – and scientific replication – using data representing different populations in one's own work or in a comment. Several controversies in empirical economics are used to illustrate how and how not to behave when replicating others' work. The incentives for replication are examined, and proposals aimed at journal editors and authors are advanced that might stimulate an activity that most economists applaud but few perform.  相似文献

In this study we estimate and compare the realized range volatility, a novel efficient volatility estimator computed by summing high–low ranges for intra‐day intervals, to the recently popularized realized variance estimator obtained by summing squared intra‐day returns. Our results, derived from a Greek equity high‐frequency data set, show that realized range‐based measures improve upon the corresponding realized variance‐based ones in most cases, especially for the most actively traded stocks. The usefulness of high‐frequency data in measuring and forecasting financial volatility is apparent throughout the paper.  相似文献

Abstract We examine how structural systems can yield observed variables instrumental in identifying and estimating causal effects. We provide an exhaustive characterization of potentially identifying conditional exogeneity relationships and demonstrate how structural relations determine exogeneity and exclusion restrictions that yield moment conditions supporting identification. This provides a comprehensive framework for constructing instruments and covariates. We introduce notions of conditioning and conditional extended instrumental variables (XIVs). These permit identification but need not be traditional instruments, as they may be endogenous. We distinguish between observed XIVs and proxies for unobserved XIVs. A main message is the importance of sufficiently specifying causal relations governing the unobservables.  相似文献

We formalize the link between optimal cost-sharing contracts and the production technology in the presence of moral hazard by appealing to several well-known results from duality theory. Building on intuitions from the interlinkage literature, we show that optimal contractual structure is determined by the (i) substitution possibilities that exist between different observable factor inputs, as well as (ii) between these inputs and unobservable effort. We endogenize contractual choice using landlord characteristics as instruments, exploiting the fact that, in our dataset, landlords interact with several tenants and vice versa. The approach is applied to an unbalanced plot-level panel of cost-sharing contracts in a Tunisian village, using a translog representation of the restricted profit function. Contractual terms are found to be a significant determinant of input use and therefore lead to Marshallian inefficiency, while the optimality of the underlying contractual structure is rejected.  相似文献

Health care expenditure and economic growth: Quantile panel-type analysis   总被引:1,自引:0,他引:1  
This study uses international total health care expenditure data of 31 countries from 1986 to 2007 for exploring the causality between an increase in health care expenditure and economic growth. The empirical procedure is divided into two parts. The first is the panel regression analysis and the second is the quantile regression analysis. The estimation of the panel regression reveals that, expenditure growth will stimulate economic growth; however, economic growth will reduce expenditure growth. With regard to the estimation of quantile regression, when economic growth is quantile, in countries with low level of growth, the influence of expenditure growth on economic growth is different. In countries with medium and high levels of economic growth, the influence of expenditure growth on economic growth is positive; when health care expenditure growth is quantile, the influence of economic growth on expenditure growth is more different.  相似文献

Many developing countries have adopted the market approach for expanding the supply of child care, but little is known about the economic behavior of independent providers. Drawing on uniquely rich census data on child care providers from São Paulo, we document three main facts: (1) the stock of private suppliers is considerably larger in high-income city districts; (2) the quality of private provision – as measured by teachers' schooling, group size and equipment – is highly heterogeneous across space and increases systematically with local household income; and (3) a considerable share of centers operates below recommended (but not regulated) quality standards, especially in low-income districts. These findings are consistent with a model of endogenous entry and quality choices by heterogeneous providers. Market-driven heterogeneity in the quality of provision across space is an important consideration for the design of regulations in child care markets.  相似文献

School choice reforms give talented students the option to sort out of low-performing schools but often leave disadvantaged students behind. This study shows how a Chinese city was successful in helping its low-performing schools to catch up by encouraging talented students to sort into these schools. The city identified eleven low-performing middle schools and guaranteed elite high school admission to their top ten-percent graduates. This study documents that the policy improved school performance by 0.19-0.26 standard deviations. Using data on lottery middle school assignment, I further test for potential mechanisms, including strategic sorting and improvement in school value-added.  相似文献

In this paper, we derive a class of modified score tests robust to local and distributional misspecifications for testing spatial error autocorrelation and spatial lag dependence. The proposed tests are general enough to include several popular tests for the spatial dependence as special cases. Moreover, we show that the popular test statistics proposed by Burridge (1980) and Anselin et al. (1996) are robust to distributional misspecification although they are derived under normality assumption.  相似文献

We show that estimates of the half‐life of deviations from the law of one price are biased when their precision is not taken into account when aggregating data for different types of goods. Using a comprehensive dataset with monthly price data for 124 homogeneous products across regions in Denmark over the period 1997–2010, we find a large positive aggregation bias. On average, we find that the half‐life is 8.4 months when taking the bias into account, compared with 28.7 months when applying the standard method. The heterogeneity in the estimated half‐life can be explained by price stickiness, distance between regions, and whether the good is traded or non‐traded.  相似文献

This paper investigates nonlinear effects of government debt on private consumption. The estimated consumption function shows smooth regime switching depending on the debt-to-GDP ratio, and a higher level of government debt crowds out private consumption to a greater extent.  相似文献

We add a gift in appreciation of the subject’s contribution to a social reference treatment successfully proven to trigger higher donations, and find that the share of people contributing decreases significantly, thereby eroding the original treatment’s capacity to increase donations.  相似文献
