Are microfinance markets monopolistic?

Do microfinance institutions (MFIs) operate in a monopoly, monopolistic competition environment or are their revenues derived under perfect competition markets? We employ the Panzar–Rosse revenue test on a global panel data to assess the competitive environment in which MFIs of five selected countries operate: Ecuador, India, Indonesia, Peru and Philippines, over the period 2005–2009. We estimate the static and the dynamic revenue tests, with analyses of the interest rate and the return on assets. We control for microfinance-specific variables such as capital-assets-ratio, loans-assets and the size of the MFI. The analyses also account for the endogeneity problem by employing the fixed-effects two-stage least squares and the fixed-effects system generalized method of moments. Our results suggest that MFIs in Peru and India operate in a monopolistic environment. We also find weak evidence that the microfinance industry in Ecuador, Indonesia and Philippines may operate under perfect competition.     

Are Australia's tourism markets converging?

Many governments in low-income countries have promoted voluntary health insurance schemes in recent years, with the principal aim of improving access to services amongst those working in the informal economy. Few attempts to understand demand for such schemes exist, particularly in light of the importance of informal social security arrangements for many households. A model of demand for health insurance is developed reflecting this context, and estimated using data from Vietnam. The results show that informal financial networks may crowd out government promoted health insurance. Implications for theory and policy are discussed.     

Are cyclical patterns of international housing markets interdependent?

This paper investigates the relationships among the US, UK, and Canadian housing markets from two aspects: the driving forces of housing cycles and the structures of correlation coefficients in different phases of housing cycles. The results indicate that the structures of driving forces and correlation coefficients are deeply hinged on the international housing markets. For the US and Canada pair, the driving forces of cyclical patterns are related to each other and the regime-switching correlation coefficients are always positive. However, for the US and UK pair and the UK and Canada pair, the driving forces are independent and there is no consistent pattern for the correlations.     

Are Islamic stock markets efficient? A time-series analysis

This article investigates the weak-form informational efficient hypothesis for three major Islamic stock markets (world, emerging and developed). Unlike previous studies, we applied different parametric and nonparametric tests to investigate efficiency in the short and long horizons. Using recent data over the period May 2002–June 2012, we developed a time-series analysis of Islamic stock price dynamics in the context of the recent global financial crisis (2008–2009). Our analysis offers two interesting results. First, emerging Islamic stock markets seem to be less efficient than developed Islamic markets, suggesting interesting investment opportunities and diversification benefits from this region in both the short run and the long run. Second, nonrejection of the cointegration hypothesis for developed Islamic markets and the global conventional stock market point to efficiency for the former in the long term, even if it is inefficient in the short term. This finding has at least two economic and political implications: (i) investors who seek moderate risk would do well to opt for Islamic funds in developed countries, particularly as they share the same tendency and provide similar expected returns in the long term as conventional funds, (ii) Islamic financial systems can offer a useful model that can help to reform and remodel conventional financial institutions.     

Are Indian rice exporters able to price discriminate? Empirical evidence for basmati and non-basmati rice

The role of exchange rate fluctuations on the pricing behaviour of Indian rice exporters in their major destination markets is examined using the pricing-to-market (PTM) model. The analysis was undertaken in a context where India has emerged as a leading exporter of rice in the world market. The study distinguishes between basmati and non-basmati rice in the analysis as the destination markets differ across these two varieties. One of the key contributions of this study is that it undertakes an analysis under 3 exchange rate models, they are: nominal, real and commodity-specific exchange rates. The results from our analysis indicated the presence of non-competitive pricing behaviour of India’s rice exporters in majority of destination markets due to both the market-specific characteristics as well as exchange rate-induced effects. The amplification of exchange rate effects was more prominent in commodity-specific exchange rate model whereas local currency stabilization was more prominent under nominal and real exchange rate models. Furthermore, the analysis showed that the commodity-specific exchange rate better predicts the PTM behaviour of rice exporters.     

How are Africa's emerging stock markets related to advanced markets? Evidence from copulas

The finance literature provides ample evidence that diversification benefits hinges on dependence between assets returns. A notable feature of the recent financial crisis is the extent to which assets that had hitherto moved mostly independently suddenly moved together resulting in joint losses in most advanced markets. This provides grounds to uncover the relative potential of African markets to provide diversification benefits by means of their correlation with advanced markets. Therefore, we examine the dependence structure between advanced and emerging African stock markets using copulas. Several findings are documented. First, dependence is time-varying and weak for most African markets, except South Africa. Second, we find evidence of asymmetric dependence, suggesting that stock return comovement varies in bearish and bullish markets. Third, extreme downward stock price movements in the advanced markets do not have significant spillover effects on Africa’s emerging stock markets. Our results, implying that African markets, with the exception of South Africa, are immune to risk spillover from advanced markets, improves the extant literature and have implications for portfolio diversification and risk management.     

Are dictators averse to inequality?

We present the results of an experiment designed to identify more clearly the motivation underlying dictators’ behavior. In the typical dictator game, recipients are given no endowment. We give an endowment to the recipient as well as the dictator. This new dimension allows us to test directly for inequality aversion. Our results confirm that the inequality between dictator's and recipient's endowment is a key determinant of the dictator's giving. As we increase the recipient's endowment from 0 to an amount equal to the dictator's endowment, the mean amount passed drops from 30 percent to less than 12 percent of the dictator's endowment, and the proportion of dictators who pass positive amounts falls from 75 percent to 26 percent. Thus the majority of dictators exhibit behavior consistent with inequality averse preferences. On the other hand, only 24 percent of dictators split payoffs equally suggesting that maximin preferences are less important drivers of dictators’ giving.     

Bank competition in transition countries: Are those markets really in equilibrium?

This paper investigates the degree of market competition in the banking industries of 17 Central and Eastern European (CEE) countries over the period 1994–2008, using the H statistic proposed by Panzar and Rosse (J Ind Econ 35:443–456, 1987). Differing from previous works, this paper applies the newly developed censored stochastic frontier model (CSFM) to test whether these markets have achieved long-run equilibrium, which is an issue overlooked by previous literature. The CSFM appears to be preferable to the conventional one that requires adding a unity to the dependent variable return on assets for all observations, making the so-derived dependent variable non-negative. One can then take the natural logarithm of this distorted dependent variable for a subsequent equilibrium test. Inconsistent parameter estimates may occur and lead to doubtful testing results. Empirical outcomes show that a majority of the banking markets under study experience rising H statistics during the sample period and are operating under monopolistic competition. Moreover, our results indicate that some CEE banking sectors are characterized as contestable markets that may have contributed to the recent deregulation and liberalization progress. More importantly, the CSFM confirms that most of the banking sectors are in long-run equilibrium, justifying the use of the Panzar–Rosse model, while the conventional, transformed dependent variable approach tends to reject the equilibrium hypothesis in more sample countries.     

Are moving average trading rules profitable? Evidence from the European stock markets

This article examines the profitability of several simple technical trading rules for 16 European stock markets over the 1990 to 2006 period. Our results indicate that increasing moving average rules indeed have predictive power being able to discern recurring price patterns for profitable trading, even after accounting for the effects of data snooping bias. To assess the profitability of different technical trading rules and strategies, we adopt the White's (2000) Reality Check (RC) test that quantifies the data snooping bias and adjusts for its effects. Our empirical results also support the hypothesis that technical trading rules can outperform the buy and hold strategy after accounting for transaction costs.     

Does decentralization contribute to efficiency? Evidence from OECD countries

This article provides evidence on the relationship between fiscal decentralization and technical efficiency. We begin the first stage of this study with a data envelopment analysis to obtain technical efficiency estimates for a sample of 23 OECD countries over the period 1992–2009. In a second stage, we explore the effects of fiscal decentralization and other control variables on technical efficiency. The results including all the control variables reveal a statistically significant negative relationship between fiscal decentralization of public expenditure and technical efficiency.     

Are Gulf stock markets efficient? Evidence from new multiple variance ratio tests

The purpose of this article is to test for the Random Walk Hypothesis (RWH) for seven stock markets in Gulf Cooperation Council (GCC) countries, and to determine the effect of the correction for thin trading. Three new multiple variance ratio tests are applied to both observed returns and returns corrected for thin trading. It is found overall that the RWH does not hold for the GCC stock markets at both daily and weekly frequencies. This evidence is particularly strong when daily returns are used, where the RWH is soundly rejected for both observed and corrected returns.     

How stock markets react to regulatory sanctions? Evidence from France

Our study of how the stock market reacts to sanction announcements by the French financial regulator from 2004 to 2017 finds that the market reacts negatively when a sanction is announced in the press. Cross-sectional regression models show that the penalties are too low to influence market reactions. Our results suggest that after the financial crisis of 2008, a plethora of news on financial wrongdoings has desensitized markets to announcements of sanctions against large companies.     

Are women expected to be more generous?

This paper analyzes if men and women are expected to behave differently regarding altruism. Since the dictator game provides the most suitable design for studying altruism and generosity in the lab setting, we use a modified version to study the beliefs involved in the game. Our results are substantial: men and women are expected to behave differently. Moreover, while women believe that women are more generous, men consider that women are as generous as men.

Have minutes helped markets to predict the MPC's monetary policy decisions?

This paper examines whether the minutes of the Bank of England's Monetary Policy Committee (MPC) have provided markets with additional information about the future course of monetary policy. The paper conducts an econometric approach based on an Ordered Probit model explaining future policy rate changes (sample 1998 to 2014), and the Vuong test for model selection, which helps to identify changes in the market assessment around the release of MPC minutes. Our results suggest that the Bank of England's published minutes of the MPC's deliberations have indeed helped markets in forming their expectations on future monetary policy decisions.     

Are stock prices excessively sensitive to current information?

The last few years has seen publication of evidence that stock prices overreact to current information. These studies have been criticized on several grounds, that the test statistics are biased and are invalid in the presence of non-stationary dividend series. This paper develops an extension of the variance bound test which is immune to these criticisms. The paper also presents evidence that the degree of excess volatility increases as the length of time the stock is held increases. Indeed, the variance bound test is satisfied for holding periods of less than two years.     

Are labour-intensive efforts to prevent pressure ulcers cost-effective?

Abstract

Background:

Pressure ulcers are a major problem in Danish healthcare with a prevalence of 13–43% among hospitalized patients. The associated costs to the Danish Health Care Sector are estimated to be €174.5 million annually. In 2010, The Danish Society for Patient Safety introduced the Pressure Ulcer Bundle (PUB) in order to reduce hospital-acquired pressure ulcers by a minimum of 50% in five hospitals. The PUB consists of evidence-based preventive initiatives implemented by ward staff using the Model for Improvement.

Objective:

To investigate the cost-effectiveness of labour-intensive efforts to reduce pressure ulcers in the Danish Health Care Sector, comparing the PUB with standard care.

Methods:

A decision analytic model was constructed to assess the costs and consequences of hospital-acquired pressure ulcers during an average hospital admission in Denmark. The model inputs were based on a systematic review of clinical efficacy data combined with local cost and effectiveness data from the Thy-Mors Hospital, Denmark. A probabilistic sensitivity analysis (PSA) was conducted to assess the uncertainty.

Results:

Prevention of hospital-acquired pressure ulcers by implementing labour-intensive effects according to the PUB was cost-saving and resulted in an improved effect compared to standard care. The incremental cost of the PUB was ?€38.62. The incremental effects were a reduction of 9.3% prevented pressure ulcers and 0.47% prevented deaths. The PSAs confirmed the incremental cost-effectiveness ratio (ICER)’s dominance for both prevented pressure ulcers and saved lives with the PUB.

Conclusion:

This study shows that labour-intensive efforts to reduce pressure ulcers on hospital wards can be cost-effective and lead to savings in total costs of hospital and social care.

Key limitations:

The data included in the study regarding costs and effects of the PUB in Denmark were based on preliminary findings from a pilot study at Thy-Mors Hospital and literature.
