A note on “Modelling exchange rate returns: which flexible distribution to use?”

Corlu and Corlu [Quant. Finance, 2014, doi: 10.1080/14697688.2014.942231] provided a novel modelling of exchange rate data for nine currencies using five flexible distributions. They stated that the generalized lambda, skew t and normal inverse Gaussian distributions ‘do a good job’. Here, we reanalyse the data and show that a distribution simpler than all of these fits at least as well as these distributions. We also find that the normal inverse Gaussian distribution provides good fits for only one of the data-sets.     

Government ownership,corporate governance and tax aggressiveness: evidence from China

This study investigates how government ownership and corporate governance influence a firm's tax aggressiveness. Using Chinese listed companies during 2003–2009, we find that compared with government‐controlled firms, non‐government‐controlled firms pursue a more aggressive tax strategy. In particular, non‐government‐controlled firms with a higher percentage of the board shareholdings and with a CEO who also serves as the board chairman are more aggressive. For government‐controlled firms, we find that board shareholding has an impact on tax aggressiveness and it does not differ between local and central government‐controlled firms. However, local government‐controlled firms in less developed regions where the implementation of corporate governance measures is generally less effective are more tax aggressive than those in other regions.     

On the asymptotic normality of some unbiased estimates

Abstract

Let X _m(n) =(X _j , n, ..., X _{j m,n} ) be a subset of observations of a sample X_n = (X_1n X _2n ... , X _nn ). Here the X_jn 'S in Xn are not necessarily independent or identically distributed, and m(n) mayor may not tend to infinity as n tends to infinity. Suppose the joint density function h_n =h_n (x _m (n); θ) of the X _jn 's in Xm(n) is completely specified except the values of the parameters in the parameter vector θ = (θ1 θ2, ... , θ _k ), where θ belongs to a non-degenerate open subset H of the k-dimensional Euclidean space Rk and k?m(n).     

Modelling Accounting Populations for Ratio Estimation in Audit Sampling

The classical ratio estimator is one of the auxiliary information estimators frequently discussed in the audit sampling literature. The major weakness of this estimator is its unreliability when accounting populations have only one-sided errors or when the error rate is low. Efforts have been made to improve the classical estimator by using techniques such as the Jackknifed ratio discussed by Frost and Tamura (1982). This paper proposes a new method to estimate the population total error based on the ratio of error over book value, i.e., taintings.

The special features of the proposed procedure are that (1) it specifically models the special characteristics of the typical accounting populations, and (2) it is the first study we know of in the audit sampling literature that uses simulation to capture the characteristics of the specific distribution of the estimator each time a confidence interval is constructed. This new approach became possible because of the recent publication of several studies on the empirical characteristics of accounting errors. Results of empirical tests indicate that the proposed method can significantly improve the reliability of the classical ratio under circumstances where the classical ratio needs improvements. Empirical comparisons are also made with a third ratio estimator under dollar-unit sampling. Again, the proposed method provides better reliability.     

Sterilization, Monetary Policy, and Global Financial Integration

This paper investigates the changing pattern and efficacy of sterilization within emerging market countries as they liberalize markets and integrate with the world economy. We estimate the marginal propensity to sterilize foreign asset accumulation associated with net balance of payments inflows, across countries, and over time. We find that the extent of sterilization of foreign reserve inflows has risen in recent years to varying degrees in Asia as well as in Latin America, consistent with greater concerns about the potential inflationary impact of reserve inflows. We also find that sterilization depends on the composition of balance of payments inflows.     

Assessing the Effect of Bilateral Collaborations on Learning Outcomes

Despite recent interest in the effects of student-driven collaborations on learning outcomes, little or no empirical investigations examine the potential benefits from collaboration between instructors of separate, but related, courses. This study proposes a learning intervention that explicitly accounts for interdependencies across courses and extends the traditional definition of collaborative learning to include the synthesis of teaching and learning in four courses through bilateral, group activities between instructors and among students. A student-performance measure assesses the intervention. Statistical results suggest that the collaborative learning intervention improved student-writing performance.     

A Dynamic Model of Export Competition, Policy Coordination, and Simultaneous Currency Collapse

This paper shows that the "price wars during booms" logic of Rotemberg and Saloner ( American Economic Review , vol. 76, 1986, 390–407) provides an explanation of contagious currency crises. The idea is as follows. When a group of countries relies on exports to a common foreign market, pressures for competitive devaluations arise. In response, competing exporters peg their exchange rates to the currency of their export market. However, it must be in each country's self-interest to adhere to its peg, and a common adverse external shock can make an existing (implicitly) cooperative arrangement unenforceable. Maintaining the arrangement requires a collective devaluation that reduces the unilateral incentive to devalue.     

THE ARTICLES OF CONFEDERATION SHOW THE NEED FOR DIRECT TAXATION? IT JUST AIN'T SO!

Historians and economists often refer to the United States experience under the Articles of Confederation as evidence against decentralised government finance. While it is true that the US government had difficulty raising money from the states during this period, we argue that these facts are a benefit of the system, not a flaw. A 'bottom-up' system of finance, such as the one that existed under the Articles of Confederation, is an important check on Leviathan and has implications for United Nations fund-raising efforts and development economics.
