Cost Heterogeneity and the Potential Savings from Market-Based Policies

Policy makers and analysts are often faced with situations where it is unclear whether market-based instruments hold real promise of reducing costs, relative to conventional uniform standards. We develop analytic expressions that can be employed with modest amounts of information to estimate the potential cost savings associated with market-based policies, with an application to the environmental policy realm. These simple formulae can identify instruments that merit more detailed investigation. We illustrate the use of these results with an application to nitrogen oxides control by electric utilities in the United States.     

An alternative to the weighted score card approach to measuring performance: An analysis of English and Welsh probation boards

The UK government published a weighted score card approach in 2003 to analyse the performance of Probation Boards in England and Wales. However, there has not been a thorough analysis of whether non-parametric methods could provide more advanced options for analysing performance than the standard Weighted Score Card approach – a variant of the Balanced Score Card. Our results show there is considerable divergence in the ranks of Probation Boards from that of the WSC when we include the input variable ‘resource expenditure’ within a DEA model, calling into question recent policy initiatives to increase efficiency in the national probation service.     

Two state capital accumulation with heterogenous products: Disruptive vs. non-disruptive goods

The paper considers the problem of a firm that, while producing a standard product, has the option to introduce an innovative product. The innovative product competes with the standard product and will therefore reduce revenues of the standard product. A distinction is made between innovative products that do or do not become even more relatively appealing as their market share grows (e.g., because of network externalities). It is shown that in the former case, which we call a “disruptive” good, history dependent long run equilibria can occur, which are in line with recent real life economic examples.     

A typology of de-coupling strategies in mixed services

A typology of a class of service systems is proposed. The typology links strategic operational objectives to the decision to de-couple work between the front and back offices of a service system. Four specific ideal types of a strategy/de-coupling mix are described; each of which has distinct operational, marketing and human resource ramifications. A type that has had significant representation in traditional literature is the “Cost Leader” type, where back-office activities are de-coupled from the front office for the purpose of lowering costs. Another traditional type representative of the craftsman legacy is the “Personal Service” type, which retains back-office tasks in the front office to pursue non-cost-oriented strategic goals. Theoretical and empirical evidence is also given for two non-traditional types: the “Kiosk” type, where all tasks remain in the front office to achieve lower costs, and the “Focused Professional” type, which de-couples front- and back-office activities to enable front-office workers to provide higher service, rather than to reduce costs. Empirically, retail bank lending systems are analyzed to support the typology.     

The true shadow price of foreign exchange

For the last half century, trade theorists, development economists, and development practitioners have been calculating what was claimed to be the shadow price of scarce foreign exchange. In fact, what they have been calculating is the social value of the receipt of a unit of a numeraire good from abroad, typically obtained from real models. In our paper, we explicitly deal with a model of a monetized economy, and we develop formulas for the social value of a unit of foreign currency, which, in general, differ from the traditional formulas.     

US household real net worth through the Great Recession and beyond: Have we recovered?

Household data adjusted for inflation show that net worth is still below its pre-Great Recession levels, unlike aggregate Federal Reserve data. Poorer and younger households both lost and recovered more net worth percentage-wise. Financial assets have recovered more than non-financial assets.
