Firm Size and Market Power in Carbonated Soft Drinks

Sutton (1998) offers us a simple way to model firm size distributions across differentiated products industries. We analyse the implications of this approach for company markups using a structural model for a specific industry. We incorporate the complexities of multi-product (brand) companies operating with different (strategic) configurations of product characteristics and stores to estimate brand markups, using Irish AC Nielsen retail data for Carbonated Soft Drinks. As a second step we estimate that market power does not increase in companies with higher market share, controlling for other factors. This challenges a traditional mind-set.

Patenting activity and elements of market structure in the Dutch manufacturing industry

Summary On the basis of econometric analysis this survey shows how patent intensity (number of patents in relation to sales) is positively influenced by technological opportunity and expected profit, and negatively by industry size and concentration. In addition, it is investigated whether patents can be used as a proxy for both inventive and innovative activity. To this question no definite answer could be given. A contradictory relationship was found between the R&D/sales ratio and the patents/sales ratio, which in this case merely shows how research based on firm data and industry data can come up with very different results. A general implication is that for studies on the Dutch manufacturing industry the aggregation from firm level to industry level should be treated with caution.The author works for Corporate Development & Economics Department of Unilever N.V.

The economics of land fragmentation in the north of Vietnam*

Land fragmentation, where a single farm has a number of parcels of land, is a common feature of agriculture in many countries, especially in developing countries. In Vietnam, land fragmentation is common, especially in the north. For the whole country, there are about 75 million parcels of land, an average of seven to eight plots per farm household. Such fragmentation can be seen to have negative and positive benefits for farm households and the community generally. Comparative statics analysis and analysis of survey data have led to the conclusion that small‐sized farms are likely to be more fragmented, and that fragmentation had a negative impact on crop productivity and increased family labour use and other money expenses. Policies which allow the appropriate opportunity cost of labour to be reflected at the farm level may provide appropriate incentives to trigger farm size change and land consolidation. Policies which tip the benefits in favour of fewer and larger plots, such as strong and effective research and development, an active extension system and strong administrative management, may also lead to land consolidation.     

Determinants of Government Aid to Katrina Survivors: Evidence from Survey Data

We analyze survey data from Mississippi coastal communities where Katrina made its final landfall. Logistic regressions indicate that government aid is helpful in dealing with one- to two-month economic disruption and long-term rebuilding but is less helpful with regard to short-term rebuilding and mitigating longer-term disruption. Our analysis (including a basic risk assessment) finds evidence that individuals receiving government aid and/or having a disability predisaster are likely to incur severe economic hardship postdisaster and that individuals with greater predisaster economic and/or social network capital seem to be less at risk. Our results underscore the importance of housing in the resumption of basic economic activity.     

The Information Contents of Aggregated Money Demand in the EMU

Estimates of aggregated and disaggregated demand-for-money functions in 7 EMU member states show that the aggregated function slightly outperforms the disaggregated functions in explaining the European demand for M3. The aggregated function appears to contain some additional information on money demand in The Netherlands and, to a lesser extent, in France. For the other countries investigated in this study information on aggregated European money demand does not add much to the explanation of demand for money in the individual countries.     

Continuity and Change in Mergers and Acquisitions: A Social Identity Case Study of a German Industrial Merger*

abstract It is crucial from an employee's point of view to perceive some degree of stability even in times of major organizational change. This paper examines the role of a sense of continuity for organizational identification after an organizational merger. We argue that mergers and acquisitions so often end in failures partly because the change is designed in discontinuous ways and employees do not feel they are doing the same job after the merger as before. Such discontinuous change engenders a critical tension between positive and negative effects of identification that has not yet been fully understood. To deepen the understanding of this tension, in‐depth interviews were conducted in a recently merged German industrial company. Based on these qualitative data we demonstrate how features of the post‐merger company structure and the way it was implemented may have eroded organizational identification. Finally, we propose a parsimonious model to be tested by future research, in which the sense of continuity is consisting of both observable as well as projected continuity.     

Human capital and economic growth in an overlapping generations model

The paper describes an aggregative optimal growth model, the essential features of which are that individuals are mortal and obtain their labor skill through educational training. The process of human capital formation is described by an education function which relates the pass rate to the educational expenditure per student. Two alternative scenarios, private and public education regimes, are separately investigated. Under the decentralized education regime, risk-neutral individuals borrow to finance their education when young. Under the centralized education regime, the cost of education is financed by taxes imposed on the workers in the economy, and the central government maximizes a long-term social target function. The equilibria of both regimes are analyzed and various comparative static results derived. It is shown that educational investment in a decentralized equilibrium is higher than that in the centralized steady state. We also establish that there exists a time discount rate at which or above which the decentralized per capita consumption exceeds that of the centralized steady state whereas for time rates of discount sufficiently near the population growth rate, the above result will be reversed.     

Housing Reform to 'Create'Jobs

Analyses of state intervention in the housing market often ignore its crippling effects, as a cause of massive unemployment Professor Patrick Minford (top), Paul Ashton (centre) and Michael Peel, of the University of Liverpool's Department of Applied Economics, call for wholesale removal tof state-imposed rigidities in housing to increase the demand for labour, restore incentives, reduce distortions in the price of land and housing
