Today, financial and economic education is a primary issue in academia and among policy makers, and there is great interest towards programmes that are able to boost it. In this paper, we test whether a programme (“treatment”) of financial education on savings, targeted to children aged 8 and 9 is effective and to what extent. We measure the interest rate required by the children before and after the treatment to accept postponing a reward, computing its variation and comparing this with that of a control group. We find evidence that the overall initiative is helpful in decreasing the level of impatience of children and the number of inconsistent choices of boys. Our findings invite to reflect on the gender neutrality of programmes of financial education. 相似文献

Voter participation rates vary widely across the 50 states and the District of Columbia. This empirical study seeks, within the context of a broadened version of the “rational voter model,” to identify determinants of this geographic variation. Using the 2014 mid-term general election, it was found that the voter participation rate across states and the District of Columbia was positively related to whether there is a close governor’s race or a close U.S. Senate race, the female labor force participation rate, the percent of the population aged 65 and over, the number of referenda on the ballot, and the degree of voting-by-mail usage. In addition, it was found that voter turnout was negatively related to the percentages of the population that are either Hispanic or Afro-American. 相似文献

After the outbreak of the global financial crisis, some governments in the EU experienced serious fiscal problems, while others were less affected. This paper seeks to shed light on the divergent fiscal performance in the EU countries before and after the outbreak of the crisis. Fiscal reaction functions of the primary balance are estimated for different groups of EU countries using quarterly data for the pre-crisis period 2001–2008 and for the crisis period 2009–2014. The pre-crisis estimations reveal some differences in persistence and cyclical reaction between different groups of countries, but in most cases little feedback from the debt stock to the primary balance. The fiscal reaction functions of the countries that eventually developed fiscal problems do not stand out. The estimations on data from the crisis period show largely unchanged persistence and counter-cyclicality but much more feedback from the debt stock, and this applies both to the crisis countries and those less affected. In spite of large deficits and accumulation of debt, the underlying fiscal reaction has become more prudent after the outbreak of the European debt crisis. 相似文献

Benchmarking is a universal practice in portfolio management and is well-studied in the optimal portfolio selection literature. This paper derives axiomatic foundations of the relative return, which underlies a benchmark-based evaluation of portfolio performance. We show that the existence of a benchmark naturally arises from a few basic axioms and is tightly linked to the economic theory. Our method relies on the use of both axiomatic and economic approaches to index number theory. We also analyze the problem of optimal portfolio selection under complete uncertainty about a future price system, where the objective function is the relative return. 相似文献

Where investments are irreversible and the future is uncertain, people in two countries can make investment decisions that turn out to be mutually inconsistent. I argue that this intertemporal coordination failure explains international business cycles in a two-currency-area setting with a floating foreign exchange rate. The sequence of events starts with an expansionary domestic monetary shock, which decreases the domestic real interest rate. Facing low transactions costs, people spend the new money relatively early in the foreign exchange market and in the foreign market for loanable funds. Domestic monetary expansion thereby changes the relative prices of domestic and foreign goods and also of goods of earlier and later stages of production. The relative price changes lead to intertemporal and international coordination failures once the monetary expansion ends and relative prices change. Domestic monetary policy thereby causes the comovement across different currency areas we observe of business cycles. 相似文献

While the literature is rich with studies on the identification of alternative types of learning processes that might exist in the real world, the identification of the determinants of the structural changes in regional learning processes is still an underexplored research field in regional innovation theories. This paper proposes the concept of regional learning paradigms and trajectories to study how alternative and more advanced learning processes arise in a region, and highlights the evolutionary path-creation strategies enabling a paradigmatic jump. By taking into consideration also learning modes typical of peripheral or declining industrial areas, generally left aside in previous theories, this new conceptual approach allows us to understand how more complex learning and innovation processes can emerge in all types of regions. From these reflections, spontaneous processes or policy recommendations to catch-up in the innovation ladder are highlighted for each type of region. 相似文献

A popular way to discipline the managers of companies or banks that got into trouble during the recent financial crisis has been to impose caps on managers' pay. Using a small extension of the standard principal–agent model, we argue that pay caps might serve the opposite purpose, because the agent might be better off with a pay cap. Specifically, we show that, given a fixed effort level to be implemented, the agent's expected utility can be decreasing in an upper bound for the agent's reward. The effect of pay caps on the general structure of optimal incentive contracts is also characterized. While an improvement of contracting information always helps the principal, it might increase or decrease the marginal cost of imposing pay caps. 相似文献

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation. 相似文献
