We study self‐selection into politics and effort once in office of citizens with different abilities and motivations in a framework where moonlighting is allowed. We find that high‐ability motivated (public‐fit) politicians exert higher effort in politics than high‐ability non‐motivated (market‐fit) politicians, and that high‐ability citizens, both public‐fit and market‐fit, may decide to enter politics. We test our predictions using a database of Italian parliamentarians for the period 1996–2006. We find evidence of advantageous selection of both market‐fit and public‐fit parliamentarians. We also show that public‐fit parliamentarians have higher voting attendance and that only voting attendance of market‐fit parliamentarians is negatively affected by income opportunities. 相似文献

In this paper, we use data on 2459 public claims made by 444 politicians from the leading US fact-checking site (PolitiFact) to provide an empirical analysis of false claims in politics, shedding light on their characteristics within an advanced democracy. The frequency of falsehoods differs according to party affiliation and topic, with false claims more likely on such topics as elections, health, labor, taxes and values. For Republican politicians, falsehood pays off in the short run, as it is associated with greater political support. 相似文献

This article contributes to our understanding of cross-border activity in general and the determinants of cross-border trade in particular by focusing on the part of cross-border sales that arise due to work-related cross-border crossings of households. We analyse empirically how cross-border consumption expenditures vary across product and services categories as well as household characteristics using representative household survey data of cross-border commuters to Luxembourg. In total, these households spend an estimated 17% of their gross annual income across the border, contributing about 10% to the total household final consumption expenditure (HFCE) in Luxembourg. Cross-border expenditure is linked to individual- and household-related characteristics and to distance between home and work. Cross-border commuters systematically exploit arbitrage opportunities that arise because of existing price level (index) differences between the country of work and the country of residence. 相似文献

This paper presents a new approach to the modeling of conditional correlation matrices within the multivariate GARCH framework. The procedure, which consists of breaking the matrix into the product of a sequence of matrices with desirable characteristics, in effect converts a highly dimensional and intractable optimization problem into a series of simple and feasible estimations. This in turn allows for richer parameterizations and complex functional forms for the single components. An empirical application involving the conditional second moments of 69 selected stocks from the NASDAQ100 shows how the new procedure results in strikingly accurate measures of the conditional correlations. 相似文献

It is generally acknowledged that the cuts in government funding for research implemented in several European countries will induce academic researchers to increase their interaction with non academic entities to promote the acquisition of external funding for research. Indirectly this implies that there will be a shift in the focus of academic scientific activity from basic to applied research via private research contracts and consultancy work. The aim of our paper is to assess the extent of the trade-off between basic research and applied activity in academic research departments. We use data for the universe of Italian academic departments over the period 2006–2011 and estimate whether increased applied activity is substituting or complementing basic research activity. We provide empirical evidence of a strong substitution effect for life sciences departments and, to a lesser extent, for engineering and technology departments, while there does not seem to be evidence of a substitution effect for departments whose scientific activity revolves around basic science. 相似文献

The focus of this paper is on Lithuania, whose government released an ambitious innovation strategy to become an innovative services hub for Northern Europe by 2015, and an innovation hub by 2020. Biotechnology has been identified as a strategic sector, and whether Lithuania will be able to achieve its ambition of a fully functioning biotechnology sectoral system of innovation will be explored. With the Lithuanian government declaring that they will intervene to achieve their innovation goals, this paper argues that sound policy intervention is possible and can be done in a way that avoids the limitations of past systemic approaches. The policy approach presented is based on a modified extended industry life cycle, and the movement of system structures through three phases – background, pre-emergence and emergence – and explains how each phase lays the groundwork for transition to the next phase. 相似文献

Using data for twelve manufacturing industries of five developed countries over the period 1980–2002, we perform a dynamic panel estimation of the long-run elasticity of TFP with respect to R&D capital. The highest elasticity is found for the US (0.39), followed by Germany (0.29–32); intermediate values are achieved by France (0.19–0.21) and Spain (0.19), while Italy records the lowest R&D impact (0.08–0.12). The latter finding, supported by an in depth analysis based on a longer time-span and more accurate data, can be ascribed to the declining R&D efforts undertaken, during the Nineties, by Italian manufacturing industries. 相似文献

The aim of this paper is to understand what economic mechanisms may cause the Law of Proportionate Effect to break down for fast-growing and shrinking firms. Recent evidence has highlighted that the first-order coefficients of quantile auto-regression of firm size decline across quantiles. Our theoretical results show that negative variance–size scaling is sufficient to yield a decline in quantile auto-regression coefficients if firm log-size is Laplace-distributed, conditional on size one period ahead. However, it is sufficient only for declining auto-regression coefficients for fast-growing firms under Asymmetric Laplace conditional log-size if skewness is decreasing with size. In other words, if the growth of large firms is less dispersed and more left-skewed, size is a disadvantage for the growth of fast-growers, but not necessarily an advantage for fast-decliners. Thus, size-related determinants of negative growth skewness, such as diseconomies of growth, market power, and managerial attention issues, impact on how the LPE is violated. Using data on Dutch manufacturing companies from the Business Register of Enterprises observed between 1994 and 2004, our empirical estimates of quantile regression models confirm the evidence of declining quantile regression coefficients for small–medium firms (20–199 employees) mainly in the right-most quantiles, and for the same subsample, we find that growth rates variance and skewness are decreasing with size. The theoretical propositions of the paper are thus corroborated. 相似文献

We study a class of stochastic Overlapping generations (OLG) economies that have one-memory equilibria, that is equilibria
that are determined by the current and past realizations of the states of uncertainty. This class is negligible, but important.
In particular, it contains all the known examples of nonexistence of recursive equilibrium. We show that, within this restricted
domain, the existence of recursive equilibrium is actually typical, and such examples are therefore nonrobust.
