This paper attempts to combine the political economics models on separation of powers between the legislature and the executive with public choice theories on the behavior of the judicial branch. We obtain a model of political accountability and checks and balances with up to three government branches: the executive, the legislature and the judiciary. We conclude that an independent judiciary improves the political accountability of democratic systems relative to the political economics models with two government branches. An accommodating judiciary, however, changes the distribution of political rents without improving accountability. 相似文献

This article used a data set containing information on 1267 households from Kuwait to investigate the determinants of demand for medical care services by examining households’ out-of-pocket expenses. To deal with the problems associated with households’ health expenditure data, a two-part model (TPM) was estimated. Given Kuwait’s demographic composition, the model was estimated for full sample, nationals only and expatriates only. Prior to estimating the model, tests were conducted to select a transformation that reduces problems associated with heteroscedasticity and non-normality of the errors. In addition, tests were performed to determine if differences in the estimated coefficients across population groups were statistically significant. 相似文献

Developing markets have increasingly gained prominence in the world economy, but the domestic factors behind this success are not well established. This uncertainty may interfere with multinational expansion plans. In this article, we examine several macroeconomic and institutional factors affecting Brazilian outward foreign direct investment in 17 destination countries. We applied a pooled ordinary least squares regression over the 2001–2014 period. The findings suggest that macroeconomic factors are still statistically significant to explain investment abroad, but several institutional factors such as corruption have emerged, having a negative effect and political violence having a positive effect on Brazilian outward foreign direct investment. 相似文献

There are two types of stock price manipulation examined in the theoretical literature: (1) insider trading, which involves private information that is true and (2) the public spreading of fraudulent false information. While there is a large empirical literature on insider trading, this is the first empirical article to examine the impact of false, fraudulent public information on stock prices and trading volume. We find that such false information, even after being denied by a credible source such as the SEC, generates both abnormal returns and abnormal trading volume. We also find that the effects of the false information on security returns and volume can be persistent for at least 2 weeks. In addition, we show that perpetrators of false news attacks can make potentially large profits from such market manipulations. 相似文献

The present paper is a methodological contribution introducing a disaggregated physical productivity accounting framework in vertically (hyper‐)integrated terms, establishing a direct correspondence between Supply–Use Tables and Pasinetti's (1973, 1988) theoretical magnitudes. As an empirical application, we computed productivity indicators and indexes of direction of technical change at the subsystem level for the case of Italy during 1999–2007. Our findings suggest that: (a) only 60 per cent of productivity growth accrued to real wages, (b) the degree of mechanization increased, (c) the most dynamic subsystems correspond to consolidated sectors, and (d) technical change has almost always been capital intensity increasing. 相似文献

This paper studies the effects of domestic and foreign demand impulses in euro area economies following the Great Recession of 2008–2009 and the Eurozone crisis of 2011–2012. Using a global Input–Output framework we apply a set of metrics to assess spillover effects of international trade in intermediates triggered by the dynamics of final demand. Our findings suggest that while cross-country trade spillovers have played a crucial role during the Great Recession, they have had a moderate impact when compared with the role of domestic sources of final demand during the Eurozone crisis. Hence, a strategy of coordinated fiscal austerity cannot be sustained by empirical evidence. 相似文献

This paper looks at a relatively unresearched but important area in money and banking – namely the provision of currency by the Central Bank. One of the most important functions of Central Banking is the provision of liquidity to the economy. However, in fulfilling this function, Central Banks have to be prepared for unexpected money demand shocks as well as production, transportation and cost of capital constraints. The paper develops a dynamic cost minimizing note inventory model that solves for the Central Bank’s optimal note order size and frequency. As part of the modeling exercise a value at risk model is used to solve for an inventory “cushion.” 相似文献

This paper investigates change in idiosyncratic volatility estimated by individual security. We find that a significant portion of securities contains long periods of increasing or decreasing idiosyncratic risk. The series of idiosyncratic risk though are unlikely to have a life-long deterministic trend, and can be often characterized by a long memory process. Our evidence suggests that the proportions of securities with rising and declining risk continuously change, which in turn affects fluctuations of the market average. This evidence implies that an average idiosyncratic risk may not be a good representative of the dynamics in risk of a given security. We demonstrate that the companies with an increasing idiosyncratic risk tend to have deteriorating performance, and investigate factors behind these empirical observations. 相似文献

This paper is the first in the literature to examine the determinants of US credit card penalty fees. Many critics of credit card fees – including a number of US Senators – have argued that credit card penalty fees reflect banks’ market share. Using a unique data set we find that fees are increasing in customer risk which supports the position of defenders of penalty fees, such as banks. However, our finding that fees are increasing in a bank's market share is consistent with the concerns expressed by politicians and regulators. We also find card penalty fees are direct substitutes for card interest rates. 相似文献

In search engine marketing, such as on Google, advertisements' ranking and prices paid per click result from generalized, second-price, sealed bid auctions that weight the submitted bids for each keyword by the quality of an advertisement. Conventional wisdom suggests that advertisers can only benefit from improving their advertisement's quality. With an empirical study, this article shows that quality improvements have complex effects whose returns are actually unclear: 5% of all quality improvements to an advertisement lead to higher prices (measured by price per click) per keyword, 100% to a higher number of clicks, 53% to higher costs for search engine marketing, and 37% to lower profits. Quality improvements lead to higher weighted bids, which only lower prices if they do not improve the ranking of the advertisement. Otherwise, better ranks likely lead to higher prices. A decomposition method can disentangle these effects and explain their effects on search engine marketing costs and profits. Finally, the results indicate that advertisers benefit if they lower their bids after improvements to advertising quality. 相似文献
