Minimum quality standard regulation under imperfect quality observability

Minimum quality standards (MQS) constitute an important regulatory tool that can be used to raise product qualities, to benefit consumers and to increase market participation. One of the main assumptions in the existing literature is that firms must comply with standards. Nevertheless, in many industries, and in particular the service industry, quality observability and enforceability are not perfect. Some low quality firms do not comply with standards. What are the welfare implications of an MQS regulation in such an environment? We develop a price competition model of vertical differentiation that accounts for these empirical observations. Contrary to well-established results in the literature, MQS can increase quality disparity between firms and raise hedonic prices. Some consumers get hurt and market participation decreases.     

Stock and credit market expansion and economic development in emerging markets: further evidence utilizing cointegration analysis

This paper empirically investigates the relationship between equity and credit market development and economic growth, in a sample of five very important ‘emerging’ markets. In particular, employing a multivariate time-series methodology to test for long-run trends and causality between variables that proxy for stock market development, credit market development and economic development. The results seem to suggest that equity markets have a role to play only in relatively liberalized economies, like Chile and Mexico. In financially repressed economies, like India, the equity market does not affect real sector growth. Furthermore, the banking crises in the 1980s and 1990s in Chile and Mexico resulted in a negative relation between economic growth and the credit market. In South Korea, equity and credit markets both affect economic growth, but not vice versa. In countries where the nature of the stock market has been speculative, like Taiwan, a negative relationship is detected between equity market development and economic development.     

Airport slot allocation: a time for change?

The increasing imbalance between airport capacity and traffic resulted in exceptional congestion and delays drawing the attention of aviation policy makers towards airport demand management for the allocation of scarce airport slots. Attempts to bring forward airport demand management measures in the form of airport slot allocation were not widely adopted and have not flourished in practice. This paper aims: (i) to apply a methodological framework for the selection of the most suitable slot allocation strategy for various types of airports, (ii) to explore potential impacts such that measures or strategies can bring about, and (iii) to assess the suitability of the existing airport pricing scheme and the potential implementation of a new policy regime aiming to bridge the gap between growing traffic and scarce airport capacity.     

Resource management in software as a service using the knapsack problem model

This paper proposes a resource allocation model for “Software as a Service” systems that maximizes the service provider's revenues and the resource utilization under a heavy load. Employing the elasticity of virtualized infrastructures, the proposed model dictates that system resources must be fully exploited by incoming jobs, even if they do not satisfy their requirements completely. This yields a higher Service Level Agreement violation probability, which is mitigated by the assignment of more resources when these become available. The problem is deduced to the Fractional Knapsack problem and the heuristic solution is implemented in the frame of a SOA environment.     

The role of structure and agency in management accounting control change of a family owned firm: A Greek case study

This study seeks to understand the changes in management accounting controls in a large Greek company (pseudonym: FA), with a focus on understanding the role of structure and agency in this change. In order to do this, we have employed a critical realist philosophy, pioneered by Roy Bhaskar (Bhaskar, 1979; 1997). We believe that the empirics of the case, the time span under consideration, and our theoretical approach provide us with a unique opportunity to explore the role of structure and agency in changing management accounting controls within the case firm. Our analysis revealed that changes in management control practices in FA were a function of different interacting structural conditions as mediated through human agency. This paper contributes to the debate about how to conceptualise agency and structure in management accounting control change (Kilfoyle and Richardson, 2011). Our analysis also demonstrates that the ‘dualism’ approach to agency and structure will result in a better analysis of management accounting control changes within firms.
