Country factors and the investment decision-making process of sovereign wealth funds

In this paper, we examine the complex decision-making processes that lead to sovereign wealth funds' (SWFs’) choice of investment location. Using a two-tiered dynamic Tobit panel model, we find that country-level factors do not have the same impacts on the investment decision and the amount to invest and that SWFs tend to invest more frequently and at higher amounts in countries in which they have already invested. More specifically, we find that SWFs prefer to invest in countries with higher political stability, whereas they are more prone to invest large amounts in countries that are less democratic and more financially open. Our results also lend support to the idea that SWFs are prudent in their choice of a target country with regard to their investment decision but behave as more opportunistic investors with regard to the amounts to be invested.     

Understanding the politics of bailout policies in non-Western countries: The use of sovereign wealth funds

This article examines bailout policies in non-Western states through selected case studies of financial bailouts in Hong Kong and Singapore between the 1960s and 1990s. Given their structural similarities and extreme openness, standard explanations would expect to find similar policy responses over this period. However, between the 1960s and 1990s, bailout policies differed greatly between the two countries, particularly with respect to the use of their sovereign wealth funds (SWFs). This article also shows that the differing uses of SWFs reflected the respective regulatory environments. In line with an emerging stream of studies in comparative politics, the present article finds that these differences take root in the institutional settings of the respective countries and vary across state-business relations.     

Calculating the real return on a sovereign wealth fund

We present a new methodology for calculating the real return on sovereign wealth funds (SWF) that share the investment objective of maximizing international purchasing power in terms of goods and services. Specifically, we modify the traditional approach for deflating the nominal return along three dimensions: the aggregator formula, the measure of international prices and the weighting scheme. We argue that a geometric average of price levels is an appropriate aggregator formula for capturing the deflationary effects of imports increasingly originating from low‐cost countries, and that import prices paid by the SWF owner and weights reflecting the owner's import pattern are consistent with the investment objective. Our proposed approach, using the Norwegian Government Pension Fund Global as an illustration, raises the estimated average annual real rate of return over the sample period of 1998–2012 from 3.1% to 4.9%.     

Optimal Delegation

We analyse the design of decision rules by a principal who faces an informed but biased agent and who is unable to commit to contingent transfers. The contracting problem reduces to a delegation problem in which the principal commits to a set of decisions from which the agent chooses his preferred one. We characterize the optimal delegation set and perform comparative statics on the principal's willingness to delegate and the agent's discretion. We also provide conditions for interval delegation to be optimal and show that they are satisfied when the agent's preferences are sufficiently aligned. Finally, we apply our results to the regulation of a privately informed monopolist and to the design of legislatives rules.     

Delegation and Threat in Bargaining

Two principals (“nations”) appoint one agent each to bargain over the provision of a public good. Two institutional set-ups are studied, each with a different level of authority given to the agents. Here authority means the right to decide the own side's provision if negotiations break down. In equilibrium the principals choose agents with preferences differing from their own. The low-authority equilibrium Pareto dominates (with regard to the principals) the case of the principals deciding on the provisions simultaneously (autarchy). The high-authority equilibrium is Pareto dominated by the low-authority equilibrium and it may even be dominated by autarchy.Journal of Economic LiteratureClassification Numbers: C71, and C72.     

Gauging potential sovereign risk contagion in Europe

This study adopts the CoVaR methodology to analyse the tail risk relationships among European sovereigns, which provide arguably important information for policymakers to identify countries that should come under close scrutiny during the current debt crisis.     

The impact of sovereign risk on bond duration: Evidence from Asian sovereign bond markets

This paper examines the effect of sovereign risk on bond duration. We compare the sovereign risk-adjusted duration for U.S. dollar-denominated Asian sovereign bonds with their Macaulay duration for both investment grade bonds and speculative grade bonds. We find that the sovereign risk-adjusted duration is significantly shorter than its Macaulay counterpart for all bonds, regardless of their bond rating and their maturity. Further, the “shortening” effect of sovereign risk on duration gets stronger as bond rating deteriorates and in recessionary conditions. Our findings provide strong support for the importance of adjusting for sovereign risk when bond portfolio managers apply the popular duration measure to hedge interest rate risk.     

The elusive costs of sovereign defaults

The evidence supporting the presence of output losses associated with sovereign defaults is based on annual observations and suffers from measurement and identification problems. This paper examines the impact of default on growth using quarterly data and finds that output contractions precede defaults and that output starts growing after the quarter in which the default took place. This indicates that default episodes mark the beginning of the economic recovery and that the negative effects of a default on output are likely to be driven by the anticipation of default, independently of whether or not the country ultimately decides to validate it.     

试论会计委派制

由于我国会计管理体制和监督制约机制还不够规范健全,造成会计信息失真问题普遍存在,它扰乱了会计工作的正常秩序,阻碍了经济发展,因此,会计委派制应运而生,它是对现行会计监督机制和会计人员管理体制的一项重大改革,也是建立社会主义市场经济和加强国家宏观经济调控的迫切需要。会计委派制有利有弊,只有提高对会计委派制的认识并加以完善,才能使会计委派制这一新生事物对经济发展发挥更大的作用。     

Financial stress and sovereign debt composition

Using a panel of 13 advanced economies for the period 1980–2012, we find that periods of impaired financial intermediation mainly accrue to maturity mismatches in sovereign debt. Thus, a higher (lower) share of short-term (medium and long-term) debt leads to an increase in the financial stress index. From a policy perspective, our work suggests that debt management policies translated into longer average maturities of sovereign debt not only reduce the expected debt servicing cost, but also mitigate strains in the financial sector.     

The trajectory of wealth in retirement

In this paper, we develop a measure of household resources that converts total financial and non-financial assets, plus annuity-like assets (mainly, Social Security and defined-benefit pensions) into an expected annual amount of wealth per person in retirement. We use this measure, which we call “annualized comprehensive wealth,” to investigate spend-down behavior among a panel of older households in the Health and Retirement Study (HRS) from 1998 to 2006. Our analysis indicates that for most retired households, comprehensive wealth balances decline much more slowly than their remaining life expectancies, so that the predominate trend is for real annualized wealth to rise significantly with age over the course of retirement. Comparing the estimated age profiles for annualized wealth with profiles simulated from several different life-cycle models, we find that a model that takes into account uncertain longevity, random medical expenses, and intended bequests lines up best with the broad patterns of rising annualized wealth in the HRS.     

Evolution of wealth inequality in China

Household wealth is a key indicator that reflects national economic competiveness and individual income levels. The distribution of wealth is central for evaluating social justice in a country. This article uses a data set composed of the 2002 China Household Income Project and the 2010 Chinese Family Panel Survey to analyze the level of wealth and wealth inequality in China during 2002 and 2010. The analysis decomposes the evolution of wealth inequality during that period in terms of the structure and composition of wealth. The findings show that there was a large increase in the quantity of wealth and wealth inequality between 2002 and 2010. The level of wealth in 2010 was four times that of 2002, and housing assets were the greatest component of overall wealth in 2010. Wealth inequality also rose dramatically after 2002, with the Gini coefficient of the distribution of wealth increasing from 0.538 in 2002 to 0.739 in 2010. The rapidly escalating price of housing has been the main contributor to increasing wealth inequality in recent years.     

Intergenerational wealth transmission in Great Britain

We document the intergenerational wealth transmission between adult offspring and their parent's using the Wealth and Assets Survey for Great Britain. We estimate an intergenerational wealth elasticity of 0.4 and Rank-Rank elasticity of 0.3 and find intergenerational wealth transmission for individuals in their 60s is lower than for those currently aged in their 30s and early 40s, though rank based estimates are stable. Our estimation results imply that the intergenerational wealth elasticity is 3.8 percentage points higher when comparing people with those the same age 6 years previously suggesting strong evidence of higher intergenerational wealth persistence in younger age cohorts. Taken together, the findings have important implications for future wealth inequalities and must be addressed.     

Fashion and wealth accumulation

Summary. This paper examines the influence of fashion on wealth accumulation in an economy with two groups of agents. Fashion is modelled as an externality generated by a particular dependence of individual agents' time preference on the two groups' per-capita consumption habits. It is shown that fashion causes excessive wealth fluctuations in the sense that stronger and more persistent fashion is more likely to generate limit cycles in wealth. Opposite to intuitive arguments , however, the externality in fashion does not necessarily generate instability in wealth. In a special case, equilibrium consumption and wealth are stable but the optimal ones that internalize the externality are locally unstable. Whether equilibrium consumption is excessive relative to optimal consumption depends on the distribution as well as the aggregate level of wealth.

“Burden sharing” in sovereign debt reduction

We examine a concerted debt reduction deal between a sovereign debtor, a private creditor, and an official creditor, who insures the deposits of the commercial bank. Our results show that a weakening of the financial position of the commercial bank reduces the contribution of the commercial bank and increases that of the official creditor, without affecting the net terms faced by the debtor. This result is robust to changes in seniority. Moreover, leaving both creditor values unchanged requires that commercial banks retire debt at “unfairly” high prices, while official creditors make a net contribution.     

Delegation and Information Sharing in Cournot Duopoly

Information sharing in oligopoly has been analyzed by assuming that firms behave as a sole economic agent. In this paper it is assumed that ownership and management are separated. Contrary to the classical result of information sharing in a Cournot duopoly with private cost information, the paper shows that information sharing is no longer always a dominant strategy and expected consumer surplus is no longer always decreased. The paper determines the circumstances under which information is exchanged and analyzes its welfare consequences.      

Delegation of Decision-Rights for Wetlands

Different nutrient abatement activities jointly determine water quality. Policies are determined by governments at central and local level, implying that decisions can be affected by strategic considerations. In this article, decentralization of wetland policies is analyzed with regard to the environmental and economic consequences. A two-stage game is used to investigate strategic abatement decisions regarding nitrogen fertilizer reductions, waste water treatment plant phosphorus reductions and wetlands, assuming that wetland decision can be decentralized. It is shown that under particular circumstances, strategic consideration may imply that a central government undertakes more abatement than socially optimal, but in most cases the opposite is likely to occur. Decentralization of wetland decisions is advantageous to the central government but only benefits the local government if its wetland technology is considerably more efficient that the central government’s. This paper explains why local governments often hesitate to take on additional responsibilities for environmental management, and identifies conditions under which local governments make smaller losses or even gain from delegation. The results also contribute to understanding how strategically optimal matching grants are chosen when governments only take into account their own direct costs of abatement and the central government needs to satisfy the local government’s participation constraint.

Delegation and commitment in durable goods monopolies

This paper studies a simultaneous-move infinite-horizon delegation game in which the principal of a durable goods monopoly entrusts pricing decisions to a manager who enjoys consuming her monetary rewards but dislikes production effort. The delegation contract allows for continual interference with managerial incentives: in each period the principal rewards the manager according to her performance. We show that when the cost of delegation is low relative to profits, the principal can attain the precommitment price plan in a perfect rational expectations equilibrium. The paper analyzes the robustness of this result under alternative specifications of timing and objectives. We also provide a numerical characterization of the equilibrium strategies for the case of linear-quadratic payoffs.
