This paper is the first to employ a multivariate extension of the LHAR–CJ model for realized volatility of Corsi and Renó (2012) considering continuous and jump volatility components and leverage effects. The model is applied to financial (S&P 500), commodity (WTI crude oil) and forex (US$/EUR) intraday futures data and allows new insights in the transmission mechanisms among these markets. Besides significant leverage effects, we find that the jump components of all considered assets do not contain incremental information for the one-step ahead realized volatility. The volatility of S&P 500 and US$/EUR exchange rate futures exhibits significant spillovers to the realized volatility of WTI. Moreover, decreasing equity prices appear to increase volatility in other markets, while strengthening of the US$ seems to calm down the crude oil market.  相似文献

This paper sought to establish how technically efficient Post Office Counters is nationally and regionally. The method by which this was determined is data envelopment analysis, applied to data for 1989 on 1281 Crown post offices. The input used was labour, and outputs consisted of average waiting times as a measure of quality of service, and nine different categories of counter transactions. Nationally it was found that technical efficiency could be significantly improved by making more efficient use of labour inputs and reducing average waiting times. Wide disparities were found in regional efficiency and it was hypothesized that these relative differences were due to differing working practices, turnovers of staff and local labour market conditions. It was also concluded for the period studied that some structural inefficiency existed due to the existence of inefficient working practices and the lack of computerization of transaction procedures.  相似文献

We define rationality and equilibrium when states specify agents’ actions and agents have arbitrary partitions over these states. Although some suggest that this natural modeling step leads to paradox, we show that Bayesian equilibrium is well defined and puzzles can be circumvented. The main problem arises when player j's partition informs j of i's move and i knows j's strategy. Then i's inference about j's move will vary with i's own move, and i may consequently play a dominated action. Plausible conditions on partitions rule out these scenarios. Equilibria exist under the same conditions, and more generally ε equilibria usually exist.  相似文献

I describe a strategy for structural estimation that uses simulated maximum likelihood (SML) to estimate the structural parameters appearing in a model's first‐order conditions (FOCs). Generalized method of moments (GMM) is often the preferred method for estimation of FOCs, as it avoids distributional assumptions on stochastic terms, provided all structural errors enter the FOCs additively, giving a single composite additive error. But SML has advantages over GMM in models where multiple structural errors enter the FOCs nonadditively. I develop new simulation algorithms required to implement SML based on FOCs, and I illustrate the method using a model of U.S. multinational corporations.  相似文献

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low‐skilled and high‐skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the productivity advantage of high‐skilled workers in the performance of complex tasks. I study the firms’ assignment problem under two labor market regimes, which capture the polar cases of fully flexible wages and a binding minimum wage for low‐skilled workers. Since the minimum wage lowers the skill premium, it increases the range of tasks performed by high‐skilled workers, which enhances the stock of knowledge within firms to solve complex tasks and reduces the mass of active firms. In a setting with fully flexible wages trade does not affect the firm‐internal assignment of workers to tasks. On the contrary, if low‐skilled wages are fixed by a minimum wage, trade renders high‐skilled workers a scarce resource and reduces the range of tasks performed by this skill type with negative consequences for the human capital stock within firms. In this case, trade leads to higher per‐capita income for both skill types and thus to higher welfare in the open than in the closed economy, whereas – somewhat counter‐intuitive – inequality between the two skill types decreases, as more low‐skilled workers find employment in the production process.  相似文献

The Energy Independence and Security Act of 2007 increased the amount of corn ethanol that must be blended into motor vehicle and other fuels as part of the renewable fuel standard. The purpose of this article is to look at how the increase in demand for corn influenced the profitability and downside risk of farms. We conducted this investigation using annual data for more than 300 farms in Kansas from 1997 through 2014. We find that the probability of a farmer’s experiencing a negative return on equity (i.e. the ‘downside risk’ of farming) decreased by 25 percentage points after 2007.  相似文献

We estimate monetary policy rules for six Central and Eastern European Countries (CEEC) during the period when they prepared for membership to the EU and monetary union. By taking changes in the policy settings explicitly into account and by splitting up the exchange rate impact into two different components we significantly improve estimation results for monetary policy rules in CEEC. We uncover that the focus of the interest rate setting behaviour in the Czech Republic, Hungary and Poland explicitly switched from defending the peg to targeting inflation. For Slovakia, however, there still seemed to be on ongoing focus on the exchange rate. Finally, Slovenia and, after a policy switch, Romania exhibit a solid relation with inflation as well.  相似文献
