Whistle-Blowing Methods for Navigating Within and Helping Reform Regulatory Institutions

There are at least four important, institutional obstacles to whistle-blowing to regulatory institutions. First, regulatory institutions are often systematically understaffed and do not have the resources needed to adequately process whistle-blowing cases. Second, regulators who process whistle-blowing cases are often systematically inexperienced and do not understand the strategic importance of whistle-blowing cases. Third, regulators are often under systemic pressure from the politicians who appoint them to ignore whistle-blowing cases relevant to their sources of financial and/or ideological political support. Fourth, there are high systemic risks to whistle-blowers who blow the whistle to regulatory institutions. Nonetheless, understanding how the institutions and obstacles operate can help us understand what types of whistle-blowing methods can be used to navigate around the obstacles and within the regulatory institutions. In addition, sometimes whistle-blowing methods can help reform regulatory institutions.     

Finite sample accuracy and choice of sampling frequency in integrated volatility estimation

We consider the properties of three estimation methods for integrated volatility, i.e. realized volatility, Fourier, and wavelet estimation, when a typical sample of high-frequency data is observed. We employ several different generating mechanisms for the instantaneous volatility process, e.g. Ornstein–Uhlenbeck, long memory, and jump processes. The possibility of market microstructure contamination is also entertained using models with bid-ask bounce and price discreteness, in which case alternative estimators with theoretical justification under market microstructure noise are also examined. The estimation methods are compared in a simulation study which reveals a general robustness towards persistence or jumps in the latent stochastic volatility process. However, bid-ask bounce effects render realized volatility and especially the wavelet estimator less useful in practice, whereas the Fourier method remains useful and is superior to the other two estimators in that case. More strikingly, even compared to bias correction methods for microstructure noise, the Fourier method is superior with respect to RMSE while having only slightly higher bias. A brief empirical illustration with high-frequency GE data is also included.     

中国的双顺差、日本经验及失衡调整

我要讲的题目是"中国的双顺差:失衡与相互依赖",主要是从90年代开始,在过去十六年中的十三年,中国国际收支经常账户和资本账户同时出现了盈余,也就是出现了双顺差.这是非常特殊的现象.首先,我从国别比较的角度来透视中国出现双顺差的独特性,然后分析中国的双顺差是如何产生的.我认为,中国的双顺差主要是由加工贸易和外商直接投资推动的.     

Market Integration,Choice of Technology,and Welfare

This paper develops an international trade model where firms in a duopoly may diversify their technologies for strategic reasons. The firms face the same set of technologies given by a tradeoff between marginal costs and fixed costs, but depending on trade costs firms may choose different technologies. Market integration may induce a technological restructuring where firms either diversify their technologies or switch to a homogeneous technology. In general, market integration improves welfare. However, a small decrease of trade costs which induces a switch from heterogeneous technologies to a homogeneous technology may locally reduce global welfare. The model also shows that productivity differences lead to intra‐industry firm heterogeneity in size and exports similar to the “new–new” trade models with monopolistic competition.     

Exploration and exploitation fit and performance in international strategic alliances

Exploration and exploitation constitute two separate, potentially conflicting strategic choices for firms engaged in international strategic alliances. Our empirical study challenges the ambidexterity argument and demonstrates that exploration and exploitation are separate (though not necessarily antithetical) strategies with different antecedents and performance consequences.Our results show that while competency similarity is conducive to upstream innovative performance, prior experience with the partner is potentially damaging for this type of performance and trust and cultural distance do not play significant roles. When the motive is efficiency and downstream market performance, prior experience with the partner instead is beneficial, as are high levels of trust and low levels of cultural distance. These findings have key implications for literature on strategic fit and alliance performance.     

Internet Based Benchmarking

We discuss the design of interactive, internet based benchmarking using parametric (statistical) as well as non-parametric (DEA) models. The user receives benchmarks and improvement potentials. The user is also given the possibility to search different efficiency frontiers and hereby to explore alternative improvement strategies. Implementations of both a parametric and a non-parametric model are presented.     

Tests of the empirical classification of horizontal and vertical intra-industry trade

Tests of the Empirical Classification of Horizontal and Vertical IntraIndustry Trade. — Using longitudinal data this paper shows the separation of international trade in (a) inter-industry trade, (b) horizontal intra-industry trade, and (c) vertical intra-industry trade used in the empirical trade literature to be non-stable at the individual product level. The high level of vertical intra-industry trade mentioned in the empirical literature probably covers up many products shifting between e.g. vertical and horizontal intra-industry trade. The paper therefore questions the work of the last decade in the measurement of intra-industry trade.     

Robustness of the market model

Summary The market model specifies that the random vector of returns on risky assets is an affine function of the return on the market portfolio plus a residual which has zero conditional expectation given the return on the market. The model is important because of its intimate relation to distributional two-fund separation and the CAPM equation. This paper shows that the market model is robust to small changes in the asset supplies only if the distribution of returns is spherically generated.     

Formula Apportionment and Transfer Pricing under Oligopolistic Competition

This paper demonstrates that under conditions of imperfect (oligopolistic) competition, a transition from separate accounting (SA) to formula apportionment (FA) does not eliminate the problem of profit shifting via transfer pricing. In particular, if affiliates of a multinational firm face oligopolistic competition, it is beneficial for the multinational to manipulate transfer prices for tax–saving as well as strategic reasons under both FA and SA. The analysis shows that a switch from SA rules to FA rules may actually strengthen profit shifting activities by multinationals.
