Sovereign Risk Contagion in East Asia: A Mixture of Time-Varying Copulas Approach

This study analyzes sovereign risk contagion between four East Asian economies (China, Hong Kong, Japan, and Korea) and its structural changes through the Global Financial Crisis (GFC) and the European Debt Crisis (EDC) by applying the mixture of time-varying copulas to those economies’ credit default swap (CDS) spreads.

This article first finds a strong contagion from the US and PIIGS economies to the East Asian sovereign CDS markets and intraregional contagion within the East Asian markets. Second, the impact of contagion is different according to whether it is measured by the linear (Gaussian) or the upper tail dependence. Third, Japan plays an important role in increasing the linear dependence whereas China and Korea are crucial in terms of the upper tail dependence. Lastly, the GFC has structurally increased the linear dependence but not the upper tail dependence between the East Asian sovereign CDS markets.     

Lessons from global modelling and modellers

Two key lessons arising from ten years of global modelling are, first, that there are indeed lessons to be learned—eg ‘business as usual’ is not a viable world future, but the will to change economic, political and social structures could indeed create a decent and sustainable standard of living for all; second, many of the lessons are fairly obvious, but there is a great reluctance, even amongst global modellers, to take them into account—eg the real-world importance of politics is rarely represented in models, or the need to take great care not to mislead when publicizing results.     

2009年国际外汇市场展望——全球经济下滑与经济力量变迁的方向

该文分析指出,由于世界各国的政策制定者都在积极地干预市场,次贷危机有望在2009年得到缓解。展望2009年国际外汇市场,除日元以外的亚洲货币将持续走弱,下半年才会有一定程度回升;市场发展将呈现经济去杠杆化、全球经济继续下滑、经济力量变迁等特征,而去杠杆化将有益于美元升势和日元走强。此外,因中国和印度正处于快速工业化的进程中,劳动生产率与结构性调整均获得了巨大改进,将有利于亚洲国家货币的升值。     

A multivariate jump-driven financial asset model

We discuss a Lévy multivariate model for financial assets which incorporates jumps, skewness, kurtosis and stochastic volatility. We use it to describe the behaviour of a series of stocks or indexes and to study a multi-firm, value-based default model. Starting from an independent Brownian world, we introduce jumps and other deviations from normality, including non-Gaussian dependence. We use a stochastic time-change technique and provide the details for a Gamma change. The main feature of the model is the fact that—opposite to other, non-jointly Gaussian settings—its risk-neutral dependence can be calibrated from univariate derivative prices, providing a surprisingly good fit.

A market model with medium/long-term effects due to an insider

In this article, we consider a modification of the Karatzas–Pikovsky model of insider trading. Specifically, we suppose that the insider agent influences the long/medium-term evolution of Black–Scholes type model through the drift of the stochastic differential equation. We say that the insider agent is using a portfolio leading to a partial equilibrium if the following three properties are satisfied: (a) the portfolio used by the insider leads to a stock price which is a semimartingale under his/her own filtration and his/her own filtration enlarged with the final price; (b) the portfolio used by the insider is optimal in the sense that it maximises the logarithmic utility for the insider when his/her filtration is fixed; and (c) the optimal logarithmic utility in (b) is finite. We give sufficient conditions for the existence of a partial equilibrium and show in some explicit models how to apply these general results.     

A semiparametric model for the systematic factors of portfolio credit risk premia

The aim of this paper is to investigate the empirical relationship between daily fluctuations in the risk premium for holding a large diversified credit portfolio, which we approximate by a benchmark credit index, and some tradeable market factors which capture systematic risk. The analysis is based on an adaptive nonparametric modelling approach which allows for the data-driven estimation of the nonlinear dynamic relationship between portfolio credit risk premia and their hypothetical components. Our main finding is that the empirical weights of the systematic factors display sudden jumps during market crises and a less intense time-dependent behaviour during normal market conditions. In addition, we find that during market crises the directions of the empirical relationships are often inconsistent with ordinary economic intuition, as they are influenced by the specific circumstances of financial markets distress.

东亚一体化面临的问题及前景

经济全球化和区域经济一体化,是当今世界经济发展的两大主要趋势。近年来,东亚一体化是东亚国际关系中出现的一个新名词。从客观发展趋势和各方积极愿望看,东亚一体化已成为亚洲区域合作中富有活力、前景广阔的重要组成部分。然而,东亚一体化迄今还主要停留在理念层面,学术界对其内涵尚未取得明确的共识。东亚一体化面临多种路径选择,路径选择的正确与否将关系到东亚一体化能否进一步向前推进。     

Financial Integration in Asset and Liability Holdings in East Asia

In this article, we examine the evolution of intra-East Asian financial integration from 2001 to 2013. Most existing studies on this topic look primarily at asset holdings; we examine liability holdings as well. Using the International Monetary Fund’s Coordinated Portfolio Investment Survey data for equities, long-term debt, and short-term debt, our analysis generally supports the conventional wisdom that East Asian countries are more financially integrated with global financial centers than they are with each other. This is true for both asset holdings and liabilities and is confirmed by an econometric analysis based on financial gravity equations. However, the gap between global integration and regional integration has narrowed for asset holdings over time but not for liability holdings. The results of additional econometric analysis indicate that diversification of liability holdings can mitigate financial instability due to global financial shocks. More precisely, diversification was associated with smaller exchange rate depreciation during the quantitative easing taper tantrum of 2013. These results point to a possible benefit from strengthening regional financial integration. Deeper regional integration would reduce dependence on global financial markets for funding and hence vulnerability to global shocks.     

The Pitfalls of International Integration: A Comment on the Bush Proposal and its Aftermath

In January 2003, the Bush Administration proposed a new system for taxing corporate dividends, under which domestic shareholders in U.S. corporations would not be taxed on dividends they received, provided the corporation distributed these dividends out of after-tax earnings (the Bush Proposal). The Bush Proposal was introduced in Congress on February 27, 2003. Ultimately, however, Congress balked at enacting full-fledged dividend exemption. Instead, in the Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA) as enacted on May 28, 2003, a lower rate of 15% was adopted for dividends paid by domestic and certain foreign corporations,¹ and the capital gains rate was likewise reduced to 15%. Significantly and in stark contrast to the original Bush proposal, under JGTRRA the lower rate for dividends and capital gains does not depend on any tax being paid at the corporate level.This comment will focus primarily on the international aspects of both the Bush Proposal and JGTRRA. I will not lay out the proposal or the law in any detail. Instead, I will ask whether either the Bush Proposal or JGTRRA make sense from an economic efficiency perspective when the international implications are taken into account. I will leave to others the question of whether either the Bush Proposal or JGTRRA are sensible ways to stimulate the economy (for discussion of the effect of the 2001 tax cuts see Shapiro and Slemrod, 2001, 2002). I will also omit any discussion of the distributive effects of either the Bush Proposal or JGTRRA, which have been extensively discussed elsewhere (e.g., Tax Policy Center, 2003; Burman, Gale and Orszag, 2003).     

Commercial Real Estate Return Performance: A Cross-Country Analysis

This paper investigates the return performance of publicly traded real estate companies. The analysis spans the 1984–1999 time period and includes return data on over 600 companies in 28 countries. The return data reveal a substantial amount of variation in mean real estate returns and standard deviations across countries. Moreover, standard Treynor ratios, which scale country excess returns by the estimated beta on the world wealth portfolio, also reveal substantial variation across countries in excess real estate returns per unit of systematic risk. However, when we estimate Jensens alphas using both single and multifactor specifications, we detect little evidence of abnormal, risk-adjusted returns at the country level. We do, however, find evidence of a strong world-wide factor in international real estate returns. Furthermore, even after controlling for the effects of world-wide systematic risk, an orthogonalized country-specific factor is highly significant. This suggests that real estate securities may provide international diversification opportunities.     

Trust and Control in Network Relations: A Study of a Public Sector Setting

This study contributes to the literature by addressing the role of trust and control in public sector settings in which several organizations cooperate; its aim is to advance the understanding of trust and control in relations in which several parties are involved. The empirical study presented is a longitudinal case study of the relationships between organizational units within a municipality and a shared service center (SSC) that provides IT and administrative services. The main finding is that, compared to actors in previous studies of dyadic relationships in the private sector, actors in network relations seem to consider trust a risky option. It is less tempting to rely on a certain party when that party in turn is entangled with other parties. This situation causes a more intensive use of formal control. Another result is that increased trust between two parties might lead to more emphasis on formal control by a third party.     

From Destination- to Origin-Based Consumption Taxation: A Dynamic CGE Analysis

A switch from the current destination-based value-added taxation to an origin-based consumption tax will not be neutral in a world economy with international capital mobility and overlapping generations. This paper evaluates the macroeconomic and welfare effects of such a multilateral reform in a two-region, intertemporal general equilibrium model. The analysis isolates and quantifies income effects due to changes in generations' tax burdens, factor price repercussions and initial asset price adjustments, as well as efficiency effects that arise from endogenous labor supply and short run savings responses in a numerical simulation exercise.     

法定代表人与其公司有无劳动关系:由几起案例引发的思考

Institutional Differences and International Private Debt Markets: A Test Using Mandatory IFRS Adoption

Institutional differences between countries result in additional information risks between borrowers and lenders in cross‐border private loans. This study examines the effect of these information risks on the structure of optimal debt contracts in international (cross‐border) versus domestic private debt markets. Using mandatory IFRS adoption as an indicator for institutional changes that reduced differences between countries, I compare attributes of international versus domestic loans before and after IFRS adoption. I find that, in the pre‐IFRS period, international loans are associated with a higher credit spread, a weaker relationship between the bank and the borrower, a more diffuse loan syndicate, and less reliance on accounting‐based covenants than domestic loans. These results are consistent with incremental information risks in international debt markets that make it more costly for lenders to screen and monitor borrower credit quality, resulting in a more arm's‐length relationship between borrowers and lenders. Many of these associations attenuate after IFRS adoption, suggesting that the pre‐IFRS differences in contract terms are driven by incremental information risks related to institutional differences between countries. My findings imply that incremental information risks result in a different optimal contract in international debt contracts compared to domestic debt contracts.

Information Sharing and International Taxation: A Primer

The sharing between national tax authorities of taxpayer-specific information has emerged over the last few years as a—probably ‘the’—central issue on the international tax policy agenda. Yet this refocusing of the debate on international taxation—away from parametric tax coordination and towards strengthening information exchange—has gone largely unnoticed in the public finance literature. This paper gives an overview of this increasingly important area of international taxation, reviewing the key economic, legal, and practical concepts and issues bearing on the analysis and implementation of information exchange, and providing an account of recent policy initiatives and emerging theoretical insights.
