The impact of PPS legislation on the systematic risk of hospitals

In 1983 the government passed legislation implementing a new method of paying hospitals for Medicare inpatient services, the Prospective Payment System (PPS). Under this system the changes in economic incentives to hospitals affected the market conditions under which hospitals operate. This article investigates the impact of PPS on the financial riskiness of hospitals. Using the capital asset pricing model (CAPM), this study analyzes the systematic risk of a portfolio of four publicly traded acute care hospitals in the pre-PPS and post-PPS periods, as well as four control portfolios. It covers a pre-PPS period from 1976 to the passage of the Tax Equity and Fiscal Responsibility Act (TEFRA) and a post-PPS period through 1988. The systematic risk for publicly traded acute care hospitals increased significantly in the post-PPS period. However, the control groups also showed significant changes in systematic risk.     

The Wealth and Risk Effects of the Gramm‐Leach‐Bliley Act (GLBA) on the US Banking Industry

Abstract:   The Gramm‐Leach‐Bliley Act (GLBA) of 1999 marks the end of Depression era regulations like the Glass‐Steagall Act of 1933 and Bank Holding Company Act of 1956. These acts have restricted banks from securities and insurance underwriting business. This paper examines the impact of the GLBA on the banking industry. We find that the banking industry has a welfare gain from this law. We investigate two different categorizations of the banking industry. We find that Money Center banks followed by the Super Regional banks benefited most from this deregulation. On the other hand, banks that had Section 20 investment subsidiaries gained more than other banks in the second category. The results also show that the exposure to systematic risk for different categories of banks decreased after the passage of this law, which implies that the GLBA is fairly successful in containing the risk that accompanied the act and also created diversification opportunities. For Money Center banks, Super Regional Banks, banks with a section 20 subsidiary and banks with a new financial subsidiary, a shift in the exposure to systematic risk can explain the overall cross sectional variation in return from the deregulation. In both categorizations we find that larger banks gained more, while the overall explanatory power of profitability is not conclusive.     

The 1994–1995 Mexican Currency Crisis and U.S. Bank Stock Returns

We investigate the impact of the 1994–1995 Mexican currency crisis on U.S. bank stock returns. We use a jump-diffusion model rather than a pure diffusion model to describe daily stock returns, because the public release of unexpected information generally is associated with discrete jumps in prices. Traditional event study models pool both announcement effects and trading effects and may lead to inefficient estimators. The jump-diffusion model can separate the impact of informed trading from unanticipated public announcements. Our results indicate that the variance of the jumps is large and increases with bank size and portion of loans to Mexico.     

Tax Principles,Product Differentiation and the Nature of Competition

We analyze the choice between the origin and destination principles of taxation when there is product differentiation and Bertrand competition. If taxes are redistributed to consumers and demand is linear the origin principle dominates the destination principle whatever the degree of product differentiation and extent of economic integration. With nonlinear demand the origin principle dominates if there is sufficient economic integration. When the social value assigned to tax revenue is higher than the private value, the destination principle dominates for intermediate values of product differentiation and economic integration. The same results are also shown to hold with Cournot competition. JEL Code: F12, H20     

Evaluating the operational and profitability efficiency of a UAE-based commercial bank

This study investigates the operating and profitability efficiency of 15 branches of UAE-based commercial bank utilising the data envelopment analysis method. The results indicate that efficiency levels among the various branches vary and that there is room for improvement. Profitability efficiency appears to be higher than operational efficiency. Regarding the financial ratios analysis, a consistent effect cannot be obtained and it cannot be determined which branch has an overall position in terms of higher performance. The historical analysis of the branch network performance indicates that management should consider major operational improvement efforts to reduce employees' expenses and other operating expenses combined with an increase in the total loans portfolio. Improvement in both interest and non-interest revenues is required to increase profitability efficiency of the whole branch network.     

Will African Agriculture Survive Climate Change?

Measurement of the likely magnitude of the economic impact ofclimate change on African agriculture has been a challenge.Using data from a survey of more than 9,000 farmers across 11African countries, a cross-sectional approach estimates howfarm net revenues are affected by climate change compared withcurrent mean temperature. Revenues fall with warming for drylandcrops (temperature elasticity of –1.9) and livestock (–5.4),whereas revenues rise for irrigated crops (elasticity of 0.5),which are located in relatively cool parts of Africa and arebuffered by irrigation from the effects of warming. At first,warming has little net aggregate effect as the gains for irrigatedcrops offset the losses for dryland crops and livestock. Warming,however, will likely reduce dryland farm income immedia-tely.The final effects will also depend on changes in precipitation,because revenues from all farm types increase with precipitation.Because irrigated farms are less sensitive to climate, wherewater is available, irrigation is a practical adaptation toclimate change in Africa.     

The interaction between tourism and FDI in real estate in OECD countries

The purpose of this article is to investigate the empirical link between foreign direct investment (FDI) in real estate sector (FDIRE) and international tourism (TOUR). Panel co-integration and panel Granger causality techniques are applied to analyse both long- and short-run relationships for the case study of selected OECD countries. Our empirical results show the existence of the long-run and a bi-directional causal relationship between FDIRE and TOUR. The results provide some implications for policy-makers.     

How important is the financial sector to price indices in an inflation targeting regime? An empirical analysis of the UK and the US

This paper investigates whether there are benefits in terms of higher economic stability from incorporating stock prices into the price index targeted by the central banks. It also looks into the question of whether central banks should use stock prices as a component of the output stability index and how the index can be constructed. An optimization technique is employed to estimate weights for the various sectoral prices. The obtained weights, which depend on sectoral parameters, differ from those used in the construction of the consumer price index, CPI. Using data from the UK and the US, our analysis demonstrates that in comparison to the CPI, our measure of inflation leads to a higher output stability. Thus, in an inflation-targeting monetary policy environment, it is important to adopt a broader inflation benchmark than the CPI for the general macroeconomic stability.
