展望“里约＋20峰会”把握企业可持续发展趋势

1992年,联合国在巴西里约热内卢举办了联合国环境和发展大会,有183个国家的代表出席。当时各国已感受到生态破坏的威胁,推动了一系列的国际条约以及新的承诺,并正式提出了可持续发展的理念。时隔20年,“联合国可持续发展大会”将于今年6月在巴西里约热内卢举行,因此也被称为“里约＋20峰会”。     

Why Are Managed Care Plans Less Expensive: Risk Selection,Utilization, or Reimbursement?

This article develops a new method of decomposing the cost difference between HMO and non‐HMO plans into observed risk selection, unobserved risk selection, utilization differences, and differences in provider reimbursement rates. We implement this method using a large national sample of employer‐sponsored health insurance enrollees from the Community Tracking Study Household Survey. We find no evidence that HMO plans attract a disproportionate share of low‐risk enrollees; the US$188 difference between HMO and non‐HMO medical expenditures per enrollee can be explained by the relatively low provider reimbursement rates paid by HMO plans. This indicates there may be little need for employers to risk adjust insurance premiums or otherwise restrict employee choice of plan types.     

Expertise, Subversion, and Bureaucratic Discretion

This article examines a legislature's delegation of policy-makingauthority to an imperfectly controlled, expert bureaucrat. Thelegislature can reduce the bureaucrat's expertise advantagethrough costly investigations of its own before delegating.Further, the bureaucrat is granted discretionary bounds by thelegislature, but can subvert legislative dictates by steppingbeyond them at some cost. I analyze the interaction of preferencedivergence, investigation cost to the legislature, and subversioncost to the bureaucrat on the decision to delegate. The modelshows that, because of the equilibrium effect of subversionon discretion, bureaucrats will want subversion of legislativedictates to be difficult, while legislators want it to be relativelyeasy. It also highlights an indirect effect between preferencedivergence and discretion: preference divergence leads the legislatureto become more expert on policy matters, which leads it to delegateless.     

Price Linkages in Asian Equity Markets: Evidence Bordering the Asian Economic, Currency and Financial Crises

This paper examines price linkages among Asian equity markets in the period surrounding the recent Asian economic, financial and currency crises. Three developed markets (Hong Kong, Japan and Singapore) and six emerging markets (Indonesia, Korea, Malaysia, the Philippines, Taiwan and Thailand) are included in the analysis. Multivariate cointegration and level VAR procedures are conducted to examine causal relationships among these markets. The results indicate that there is a stationary relationship and significant causal linkages between the Asian equity markets. Nevertheless, lower causal relationships that exist between the developed and emerging equity markets suggest that opportunities for international portfolio diversification in Asian equity markets still exist.     

Asymmetric Adjustment Costs, Asymmetric Pricing and Employment: Evidence from the UK

This paper uses an asymmetric multivariate model to investigate asymmetries in employment and pricing behaviour by firms. This generalises the approach of Granger and Lee (1989) and also exploits the cross equation restrictions on the equations for prices and employment implied by a restricted cost function—the dual to a Cobb‐Douglas production function. Our results suggest that both prices and employment respond asymmetrically to shocks to costs and demand.     

Forecasting Foreign Exchange Markets Using Google Trends: Prediction Performance of Competing Models

Abstract

Foreign exchange markets affect a variety of humans and businesses worldwide and there is a wide array of literature aimed at providing more accurate forecasts of their movement. In an attempt to quantify human expectations, Google query search terms related to foreign exchange markets are used to help explain and predict foreign exchange rates between the United States’ dollar and ten other currencies during the time period of January 2004 and August 2018. We find evidence that, while Google Trends can be helpful in prediction, it is necessary to implement some sort of shrinkage or sparsity scheme on the coefficients.     

Legal Reform,Contract Enforcement and Firm Size in Mexico

The variation in legal system quality across states in Mexico is used to examine the relationship between judicial quality and firm size over the course of the 2000s, when systemic changes were taking place. Using economic census microdata and survey‐based measures of legal institutions, a robust effect of judicial quality is observed on the firm size distribution and efficiency, instrumenting for underlying historical determinants of institutions. Indicative evidence is found that the effect is strongest in more capital‐intensive industries. Market size and distance‐to‐market are also found to matter for firm size outcomes, consistent with the new trade literature.

The perilous effects of capability loss on outsourcing management and performance

The outsourcing of manufacturing activities and business processes has emerged as a prevalent business practice in many industries. Given this state, the lackluster performance of an alarmingly high proportion of outsourcing initiatives is somewhat surprising. In an effort to achieve aggressive cost savings objectives, many outsourcing engagements are associated with organizational resources being disposed of which can lead to a significant operational capability loss on the part of the outsourcing firm. Surprisingly little empirical research has dealt with the issues arising from this capability loss frequently associated with outsourcing. This study strives to address this void. Drawing on multiple theoretical perspectives, this study investigates the direct impact that capability loss has on outsourcing performance, and also the impact it has on the outsourcing firm's ability to effectively manage its relationship with the outsourcing provider. Results from our hierarchical regression analysis on 198 outsourcing initiatives suggest an inadequate capability evaluation up front can lead to a more substantive capability loss. Subsequently, we find that a more extensive capability loss has a direct negative effect on outsourcing performance. Prior studies have established the significant positive effect that developing a committed and cooperative relationship with the provider has on outsourcing performance. Our results corroborate these previous findings, and also demonstrate that capability loss inhibits the outsourcing firm's efforts to develop a committed and cooperative relationship with the outsourcing provider.
