Life-cycle direct public fiscal contributions and transfers are studied using longitudinal income tax data from 1982 to 2016 and administrative files for immigrants landed in Canada from 1980 to 2016. Relative to a comparison group comprising the Canadian-born and immigrants landed before 1980, immigrants since 1980 have a lower average net direct fiscal contribution (NDFC) during their working years due to their lower taxes and social security contributions but a higher average NDFC after 65 years of age because of reduced public pension eligibility and entitlement. Immigrants who landed at younger than 19 years old have much higher direct fiscal contributions than other age-at-arrival groups and reach their peak of contributions around 10 years earlier in life than other age-at-arrival groups. Immigrants whose age at arrival is above 65 have a less negative average NDFC than other age-at-arrival groups over the above-65 life cycle. These life-cycle age𠄁at-arrival trajectories are stable for immigrants in different landing cohorts. We apply the life-cycle estimates to project the present discounted value of lifetime NDFCs for immigrants who landed in 2016. For each landing age group, refugees and family class immigrants have negative or zero average present values of life-cycle NDFCs, much below that of economic immigrants.  相似文献

This paper aims to investigate the impact that the capital structure of a firm has on its stock price performance. We apply regression analysis at a sample consisting of Greek listed non-financial companies over the period 1998-2009, both at the full sample level and at four leverage deciles. In doing so, we test if leverage is priced as a risk factor by constructing a leverage factor. The main contribution of our work is that we diversify capital structure studies by broadening the limited work that has been accomplished on the base of leverage as an explanatory variable of returns. Our findings show that the leverage risk factor contains significant information content and that it adds a considerable portion in the explanation of stock returns.  相似文献

Behavioral economics (BE) examines the implications for decision-making when actors suffer from biases documented in the psychological literature. This article considers how such biases affect regulatory decisions. The article posits a simple model of a regulator who serves as an agent to a political overseer. The regulator chooses a policy that accounts for the rewards she receives from the political overseer—whose optimal policy is assumed to maximize short-run outputs that garner political support, rather than long-term welfare outcomes—and the weight the regulator puts on the optimal long run policy. Flawed heuristics and myopia are likely to lead regulators to adopt policies closer to the preferences of political overseers than they would otherwise. The incentive structure for regulators is likely to reward those who adopt politically expedient policies, either intentionally (due to a desire to please the political overseer) or accidentally (due to bounded rationality). The article urges that careful thought be given to calls for greater state intervention, especially when those calls seek to correct firm biases. The article proposes measures that focus rewards to regulators on outcomes rather than outputs as a way to help ameliorate regulatory biases.  相似文献

Theory asserts that individuals’ migration decisions depend more on their expectations about future income levels than on their current income levels. We find that the implementation of market-oriented reforms in post-communist countries, by forming positive economic prospects, has reduced emigration as predicted by theory. Our estimates show that migration flows are highly responsive to reforms supporting private enterprises and financial services, which provide individuals with strong signals about their future prospects. We show that reforms that improve the management of infrastructure services have no link with migration patterns, which may be an important lesson for government policy.  相似文献

This paper tests for beta-convergence and sigma-convergence in the corporate governance models, using a sample of corporate governance ratings for 198 European corporations listed on the FTSE Eurofirst 300 index. A piecewise linear regression is deployed to select a model and the Poisson pseudo-maximum likelihood estimator is also applied to estimate an exponential model. It concludes that there is statistical evidence of beta- and sigma-convergence within countries and the results suggest that institutional differences between countries are statistically relevant.  相似文献

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on vertical innovation (i.e., quality improvement) and horizontal innovation (i.e., variety expansion). Calibrating the model and simulating transition dynamics, we find that strengthening the effect of blocking patents stifles vertical innovation and decreases economic growth but increases social welfare due to an increase in horizontal innovation. In light of this finding, we argue that in order to properly analyze the growth and welfare implications of patents, it is important to consider their often neglected compositional effects on vertical and horizontal innovation.  相似文献

Many studies specify human mortality patterns parametrically, with a parameter change affecting mortality rates at different ages simultaneously. Motivated by the stylized fact that a mortality decline affects primarily younger people in the early phase of mortality transition but mainly older people in the later phase, we study how a mortality change at an arbitrary age affects optimal retirement age. Using the Volterra derivative for a functional, we show that mortality reductions at older ages delay retirement unambiguously, but that mortality reductions at younger ages may lead to earlier retirement due to a substantial increase in the individual?s expected lifetime human wealth.  相似文献

Technology and knowledge are two key components for economic growth; however, the two concepts are not consensually defined. This paper proposes a model to assess and quantify the technology contribution to the value-adding process. The methodological approach implied building an operational concept for technology that is independent of the concepts of knowledge and capital. As such, technology could be interpreted and quantified as an input parameter in a new production model. This model interprets and assesses, separately, the value contributions of the uses of technology, of knowledge and of capital in a production process, defining the Technology Index for that process. The model is applied to manufacturing sectors of seven European countries, quantifying their respective dependences on technology. A comparison of the Technology Index proposed here is made with the OECD's Technology Intensity factor, arguing that the former reflects the technology dependence better that the latter. Accordingly, a criterion for classifying the economic sectors' dependence on technology is proposed. A main contribution from this study is an objective classification criterion for technology dependence of firms and economic sectors. It also provides an easy benchmark procedure for knowledge and capital dependence between firms and sectors.  相似文献

In this paper we present a quantitative analysis of the evolution of some Internet and ICT evolution indicators. It focuses on the number of Internet hosts, the Internet penetration index, the ICT development index and the software/protocols development. In addition, we analyzed the series of most impacting events building up the Internet along the last fifty years. These analyses were carried out using the multi-logistic procedure recently proposed by the authors. Our results for hosts counting, penetration index and software/protocols development are compatible with the onset of some radical changes in the Internet technology to be currently underway and we forecast new growth rate peaks to occur by 2015. The software/protocols were found to having been powered by bursts of creativity with periods of the order of the Kuznets and Kondratiev economic cycles. Similar conclusions were drawn from the series of main events building up the Internet. Despite the clear signs of worldwide improvement in the ICT infrastructure and usage between 2002 and 2007 obtained from the ICT development index, its cross-correlation with the human development index (HDI) revealed the presence of a group of countries whose improvements in the operational ICT index are disconnected from their corresponding HDI improvements.  相似文献

Following the recent global financial crisis, questions about the mechanisms that can help countries cope with large shocks have resurfaced. This paper examines the role of the exchange rate regime in explaining how emerging market economies fared in the recent global financial crisis, particularly in terms of output losses and output rebound. After controlling for regime switches during the crisis, using alternative definitions for pegs, and taking account of other likely determinants, we find that the growth performance for pegs was not different from that of floats during the crisis. The picture is different for the recovery period 2010–2011, as pegs appear to be faring worse, with growth recovering more slowly than floats. These results suggest an asymmetric effect of the regime during and recovering from the crisis. We also find that proxies of the trade and financial channels are important determinants of growth performance during the crisis, while only the trade channel appears important for the recovery thus far.  相似文献
