Call centres and beyond: a thematic evaluation

This introduction aims to place the articles in this special edition in the context of the wider literature on call centres. The discussion is arranged around four themes: the characteristics and organisational features of call centre work, the choices and strategies that are available to manage the work, the effects of this type of work on employees and, finally, the responses and reactions of call centre staff to their work experiences. The articles selected, which are drawn from a conference sponsored by this journal, are then summarised.     

A Macroeconomic Stabilization Game: Design,Development, and Testing

The author describes a computer game involving macroeconomic stabilization policy. Students are asked to take the part of government in manipulating tax rates, expenditures, monetary policy in an attempt to influence employment and inflation in an open economy.     

HYBRID INNOVATION IN MEIJI,JAPAN*

Japan’s hybrid innovation system during the Meiji era provides a useful laboratory for examining the effectiveness of complementary incentives to patents. Patents were introduced in 1885, and by 1911 1.2 million mostly nonpecuniary prizes were awarded at 8,503 competitions. Prizes provided a strong boost to patents, especially in less developed prefectures, and they also induced large spillovers of technical knowledge in prefectures adjacent to those with prizes, relative to distant control prefectures without prizes. Linking competition expenditures with the expected market value of patents induced by the prizes permits a cost–benefit assessment of the prize competitions to be made.     

Default estimation,correlated defaults,and expert information

Capital allocation decisions are made on the basis of an assessment of creditworthiness. Default is a rare event for most segments of a bank's portfolio and data information can be minimal. Inference about default rates is essential for efficient capital allocation, for risk management and for compliance with the requirements of the Basel II rules on capital standards for banks. Expert information is crucial in inference about defaults. A Bayesian approach is proposed and illustrated using prior distributions assessed from industry experts. A maximum entropy approach is used to represent expert information. The binomial model, most common in applications, is extended to allow correlated defaults yet remain consistent with Basel II. The application shows that probabilistic information can be elicited from experts and econometric methods can be useful even when data information is sparse.

The effects of monetary policy changes on market interest rates in Greece: An event study approach

The operational procedures of the Bank of Greece underwent major changes during the 1990s. These shifts in operational strategy made interest rates the main tool of monetary policy for the first time in Greece. This paper examines the effects of changes in the bank's operational interest rates on market interest rates at eight maturities and for different operational regimes. A major feature of our study is the application of the event study methodology used in finance, which has not been employed in any previous study on this subject. We find that changes in official interest rates had a significant influence on short-term and intermediate-term rates and that this relationship was affected by the changes in the bank's operational procedure.     

Do Energy Prices Affect U.S. Investor Sentiment?

The current literature has examined the effect of investor sentiment on energy prices, but no study ever has explored the validity of the reverse question. Therefore, this article explore whether energy prices (i.e., crude oil and natural gas prices) affect U.S. investor sentiment, using the methodology of quantile regression. The empirical results document that controlling for a number of U.S. macroeconomic and financial factors, there exists a statistically significant association between oil and natural gas prices and investor sentiment. However, only natural gas prices appear to retain their statistical significance over the majority of quantiles. These findings received robust support under alternative measures of the investor sentiment index.     

Competition and efficiency in the MENA banking region: a non-structural DEA approach

The goal of this article is to empirically assess the relationship between competition and efficiency in the banking sector of Middle East and North African (MENA) countries spanning the period 1997–2011. To measure the level of competition, the article estimates the non-structural indicator known as the H-statistic, while the level of bank efficiency is estimated through the nonparametric methodology of the Data Envelopment Analysis (DEA) and the Bootstrap Data Envelopment Analysis (BDEA), respectively. The empirical results are robust under six econometric methodologies, providing sufficient evidence for the presence of a one-way (negative) Granger causality, running from efficiency to competition. The empirical findings lead to the rejection of the ‘Efficient Structure Hypothesis’, implying that increases in competition do not precede increases in cost efficiency.     

Financial Development and Economic Growth Nexus: A Revisionist Approach

In this piece, we highlight some of the salient issues and controversies surrounding the relationship between financial development and economic growth, from both the theoretical and the empirical fronts. We first discuss the controversies on the role of financial development in economic growth; and we then proceed to review the causal relationship between financial development and economic growth. We conclude that the relationship between financial development and economic growth is highly complex, and is dependent on a number of factors. Hence, the argument that financial development always leads to economic growth should be taken with extreme caution.
