We investigate volatility spillovers between two stock markets: Turkey and Brazil. Using a misspecification-robust causality-in-variance test, we find evidence supporting volatility spillovers from the São Paulo Stock Exchange to the Istanbul Stock Exchange. Moreover, the results imply that financial crises may change the nature of volatility spillovers between the two markets by adding an additional channel of volatility transmission from Turkey to Brazil. 相似文献

The role of a pension trustee is significant, which makes the recruitment and selection of labour trustees an important issue. In this article, we examine and combine aspects of two approaches to recruitment and selection: the political nomination model and the more professional HRM approach. We argue that an integrative approach would acknowledge the political, regulatory and organisational context while incorporating valid selection criteria such as domain‐specific skills and performance on the job. Such an integrated process can help trade unions in filling labour trustee positions with talented individuals who are more likely to be effective in achieving labour's goals in pension governance. 相似文献

This study shows that for firms in the Latin America and Caribbean region, bribery significantly distorts firm growth. Firms that were solicited for bribes when conducting business transactions – such as applying for permits, electricity, or water connections – have 23% lower annual sales growth than firms that do not face such solicitations. Moreover, these distortions are more severe for low-revenue-generating and young firms. Using the instrumental variables method on cross-sectional data as well as evidence from panel data, the authors show that these results are robust to different specifications and the use of different sub-samples. 相似文献

The difference between average hours worked in the US and average hours worked in Continental European countries has been increasing since the early 1970s. To explain this phenomenon, this paper develops an endogenous growth model with two key properties: agents are heterogeneous in their rates of time preference and labor skills, and the model incorporates progressive income taxes. The model is calibrated to US and German data for the periods 1971-1974 and 1986-1989. Our findings suggest that the degree of progressivity is a major factor in explaining the patterns of the US and German labor supply over time. Predictions of the model also match the distributional trends in both countries during this time period. 相似文献

In a model with finitely many agents who have single-dipped Euclidean preferences on a polytope in the Euclidean plane, a rule assigns to each profile of reported dips a point of the polytope. A point $x$ of the polytope is called single-best if there is a point $y$ of the polytope such that $x$ is the unique point of the polytope at maximal distance from $y$ . It is proved that if the polytope does not have either exactly two single-best points or exactly four single-best points which form the vertices of a rectangle, then any Pareto optimal and strategy-proof rule is dictatorial. If the polytope has exactly two single-best points, then there are non-dictatorial strategy-proof and Pareto optimal rules, which can be described by committee voting (simple games) between the two single-best points. This also holds if there are exactly four single-best points which form the vertices of a rectangle, but in that case, we limit ourselves to describing an example of such a rule. The framework under consideration models situations where public bads such as garbage dumping grounds or nuclear plants have to be located within a confined region. 相似文献

An approach to detecting plagiarism in spreadsheet assignments: A digital answer to digital cheating
Accounting instructors often experience frustration when confronted by plagiarism in student assignments. Also, they face difficulty verifying and proving cases of plagiarism. Students have increasingly found it easier to plagiarize assignments because of digitization in education. Instructors face an important pedagogical challenge due to digitization based plagiarism. Digitization, however, provides instructors with tools to address this issue. This paper showcases three tried and tested methods built into spreadsheet software to identify and detect plagiarism in spreadsheet based assignments. The first method is a manual method of hiding unique markers in files sent to students. The second method involves hiding a formula that can track plagiarism in more detail. The third method uses a program code to track issues related to authorship of assignments. These methods along with a compiled list of strategies discussed in this paper can help reduce plagiarism. 相似文献

This paper examines the effects of exchange market reform on inflation and quasifiscal deficits in developing countries. The first part presents the conceptual framework, which identifies a variety of implicit taxes and subsidies that must be taken into account (in addition to implicit taxes on exports, as emphasized by Pinto (1991)) in assessing the fiscal and inflationary effects of exchange market reform. A formula that attempts to capture explicitly these taxes and subsidies is derived. The second part applies the formula to six countries (Guyana, India, Jamaica, Kenya, Sierra Leone, and Sri Lanka). The results suggest that exchange market reform may lead to a significant reduction in reliance on the inflation tax. 相似文献

We studied how the pursuit of bilateral free‐trade agreements (FTAs) affects the likelihood of achieving multilateral free trade. We derive and compare the stable Nash equilibria of two games of trade liberalization: in the FTA game, each country can either form an FTA with one of its trading partners or both of them or none of them, whereas in the (restricted) No FTA game, purely bilateral FTAs are not permitted. The major result is that there exist circumstances under which the freedom to pursue (discriminatory) bilateral FTAs is necessary for achieving multilateral free trade. 相似文献

Newly public firms make acquisitions at a torrid pace. Their large acquisition appetites reflect the concentration of initial public offerings (IPOs) in mergers and acquisitions-(M&A-) intensive industries, but acquisitions by IPO firms also outpace those by mature firms in the same industry. IPO firms’ acquisition activity is fueled by the initial capital infusion at the IPO and through the creation of an acquisition currency used to raise capital for both cash- and stock-financed acquisitions along with debt issuance subsequent to the IPO. IPO firms play a bigger role in the M&A process by participating as acquirers than they do as takeover targets, and acquisitions are as important to their growth as research and development (R&D) and capital expenditures (CAPEX). The pattern of acquisitions following an IPO shapes the evolution of ownership structure of newly public firms. 相似文献
