Price and quality components of imports of food products into the UK

This paper analyses the principal factors responsible for the growth in the value of imports of the UK food sector, during the period 1985-90. On the basis of estimates of translog multilateral price indices it assesses the relative contribution of changes in the quality of imported products and factors other than quality to growth in import values of food products. The main conclusion is that growth in quality appears to be the principal reason for the growth in unit values of imports and the trade deficit incurred by the food manufacturing sector.     

Dynamic almost ideal demand systems: an empirical analysis of alcohol expenditure in Ireland

This paper presents a dynamic form of the Almost Ideal Demand System (AIDS). Three versions of the static AIDS model are employed to determine the preferred long-run equilibrium model and represents the short-run dynamics by an error correction mechanism. This estimation procedure is then applied to alcohol expenditure in Ireland. The estimated point elasticities are consistent with previous studies and a priori expectations. Beer and spirits are found to be price inelastic in both the short and long run. While wine is price inelastic in the short run and price elastic in the long run.     

The determinants of tendering periods for PPP procurement in the UK: an empirical analysis

The procurement of infrastructure projects via public–private partnerships (PPPs) is rising globally. PPPs are, however, often characterized by lengthy tendering periods, defined as the difference between contract notice and financial close. Tendering periods are important because they account for a significant proportion of overall project delivery time. Slow tendering deters bidders and thus reduces competition for contracts. We source data on 670 PPP projects in the United Kingdom and use a duration analysis model to empirically examine factors that impact tendering period duration. Our results reveal significant sectoral variation with projects in the health and housing sectors taking significantly longer to reach financial close. We also show that, after controlling for other factors, projects with higher capital values and projects that overlap with the timing of general elections are associated with significantly longer tendering periods. We further examine the impact of the competitive dialogue procurement method and find evidence that tendering periods have increased since 2006; the year competitive dialogue was introduced. We do, however, observe a significant reduction in the time between appointment of preferred bidder and financial close post-2006. This suggests that competitive dialogue is effective in reducing the scope for negotiations by preferred bidders holding quasi-monopoly advantages.     

Ownership structure,board composition and the market for corporate control in the UK: an empirical analysis

This paper analyses the board composition and ownership structures of a sample of companies that have been acquired and those of a matching control sample that have not. We find significant governance differences between acquired firms and the control sample. Firms with the following characteristics were more likely to be acquired: they had the same person acting as CEO and chair, a higher proportion of non-executive directors, larger institutional shareholdings and higher director shareholdings. An analysis of small firms also found evidence of higher CEO shareholdings. We also find that treating all take-overs as a single group leads to a model mis-specification which does not identify the incentive effects of board and CEO shareholdings present in non-hostile acquisitions. These results are consistent with two agency-derived hypotheses, financial incentives and effective monitoring. We also find that targets exhibit lower growth potential but do not have worse accounting performance.     

Evaluating the productive performance of UK universities as cost-constrained revenue maximizers: an empirical analysis

The study presents an empirical analysis of the relative revenue efficiency of UK universities in providing teaching and research. With government policies pressurizing the largely public-funded universities to secure efficiency in both input usage and output revenue, university producers are modelled as cost-constrained revenue maximizers. Taking explicit account of the quality of research output, the methodology uses linear programming techniques to construct nonparametric cost indirect production frontiers and to compute revenue efficiency relative to these frontiers. Revenue efficiency is then decomposed into its (output) allocative and technical components. Further analysis investigates the sources of allocative and technical inefficiencies.     

The effect of military expenditure on growth: an empirical synthesis

Using a sample of 272 meta-observations drawn from 48 primary studies, this paper conducts a meta-analysis of the empirical literature that examines the impact of military expenditure on economic growth. We find that existing studies indicate growth-retarding effects of military expenditure. The results from the meta-regression analysis suggest that the effect size estimate is strongly influenced by study variations. Specifically, we find that underlying theoretical models, econometric specifications, and data type as well as data period are relevant factors that explain the heterogeneity in the military expenditure–growth literature. Results also show that positive effects of military expenditure on growth are more pronounced for developed countries than less developed countries.     

Determinants of non-life insurance expenditure in developed and developing countries: an empirical investigation

The determinants of non-life insurance expenditure in a panel data set covering 36 developed countries and 31 developing countries for the period 2000–2011 are analysed. Results of our instrumental variable analysis indicate that economic freedom, income, bank development, urbanization, culture and law systems are the key drivers of the non-life insurance expenditure across countries. However, their impacts differ significantly between the groups of developed and developing countries, suggesting that the heterogeneity among countries in terms of the level of development plays an important role. The global financial crisis is also found to influence the direction of those effects, especially in developed countries. The article yields useful policy and economic implications for governments and multinational non-life insurance companies with regard to the development of the non-life insurance sector, an important engine for economic growth and prosperity.     

The diffusion of mobile telephony in Italy and the UK: an empirical investigation

Since its appearance mobile telephony has shown a remarkably fast diffusion pattern in most advanced countries. This paper investigates technological and economic factors that have influenced the diffusion process of cellular phones, in particular the diffusion speed and the upper limit. The epidemic model widely used in diffusion studies is summarised and discussed highlighting the evolutionary disequilibrium nature of diffusion processes. Moreover, the econometric specification of some of the models distinguishes between long-run relationships and short-run adjustments to a continuously evolving pattern. We find that the new digital technology, which coincides with increased competition in both Italy and the UK, has made the process faster and increased the saturation level in Italy, but not in the UK; in Italy only the decreasing price of the handset has affected the diffusion process, whereas we find that, in addition to that, decreasing tariffs and increasing consumption expenditures have been significant in shaping the diffusion process of mobile telephony in the UK.     

The impact of imports on price-cost margins: An empirical illustration

This article decomposes the impact of imports on domestic price-cost margins into separate price and cost effects. Using data from 24 food-processing industries, the empirical results show that although the direct impact of imports on prices is always negative, a positive net impact on price-cost margins occurs in industries characterized by low own-price elasticity of demand and diseconomies of scale. Further results show that the disciplining effect of imports is more preponderant the lower the degree of domestic competition.

Military expenditure and the rate of profit: some empirical results

This article begins with a discussion of the seminal work of Luxemburg and the related work of Mandel. Using OLS estimation methods it proceeds to test for the relationship between military expenditure, the rate of profit and other related variables in advanced industrialized countries. Using annual time-series data the estimates, together with several diagnostic tests, are undertaken for the period 1958–87 for the UK, the USA and former W. Germany.     

The effects of government expenditure on imports in the Eurozone reconsidered: evidence from panel data

This study examines the impact of government expenditure on imports. The empirical analysis is based on annual data of the euro area countries for the period 1995–2015. We employ econometric methods that mitigate heterogeneity and cross-sectional dependence. We provide empirical indications that the components of expenditure have different impact on imports demand. The findings of this study indicate that the import context of government expenditure is lower than the import context of others expenditure components. Finally, we find that an increase in government expenditure leads to an increase in imports; this implies that, ceteris paribus that it can lead to a deterioration of the trade balance.     

Aggregate health care expenditure in the United States: evidence from cointegration tests

Unlike recent studies that are based on international cross-sectional series, this paper attempts to quantify the role of the determinants of aggregate health care expenditure per capita, using time-series data for the period of 1960–87 for the United States. The paper applies the relatively new procedures of unit root testing, cointegration and error-correction modelling. The evidence supports cointegration. Although, the results indicate that per capita income, age of the population, number of practising physicians, and public financing of health care are important determinants, the age structure of the population and number of practising physicians emerge as the major determinants of aggregate health care expenditure in the United States.     

Coordination and price shocks: an empirical analysis

This paper outlines a new technique, which makes optimal control in a stochastic minimum variance framework computationally feasible. The new approach is then used to evaluate gains to policy coordination in the context of a macroeconometric model for the G-3. More specifically, we consider policy responses to a temporary price shock in a single country and in multi-country cases. The results show that coordination brings about a striking improvement in the overall control of inflation and a reduction in output costs.     

The Widening Geography of UK International Production: theoretical analysis and empirical evidence

The paper starts by defining widening and deepening patterns of international production. In a widening pattern companies and countries increase their internationalisation by spreading out their activities in more and more countries. In a deepening one they become more involved in ‘approximately’ the same countries in which they have already operated. An analysis of the a priori reasons why we might expect a widening trend, as well as the possible reasons for deepening trends, follows. The results of empirical micro- and macro-studies are then presented. The empirical work considers first the changes in the geographical network of affiliates of the UK largest TNCs in the last 30 years. This is followed by a study of the macro-network in relation to the location of UK outward FDI. Both sets of results support the hypothesis of a widening geographical trend. Some conclusions are drawn on the possible implications for strategies at the level of companies, labour organisations and governments.     

Prostitution services: an exploratory empirical analysis

This study provides an empirical analysis of the market for some male prostitution services in the UK. Flexible working hours, part-time working, and multiple job holding are considered as important labour market characteristics in this service sector. Statistical models helping explain the provision of a deviant and a more mainstream sexual service is reported, utilizing cross-section data drawn from individual prostitute advertisements. The significance of various declared intrinsic endowments of the prostitutes are examined in relation to the offer of these services, including age, ethnicity, physique, and masculine demeanour.     

Modelling public expenditure: empirical evidence from five countries

This artice considers the trends in the public expenditure/GDP ratio over the last 28 years or so, in five countries: Cyprus, France, Greece, the UK and the USA. An empirical investigation incorporating both economic and political variables is conducted into the observed pattern of the ratio for the five countries. Our results suggest that whilst some of the host of factors advanced as explanations for the size and growth of the public sector exert a significant influence, the ‘relative price effect’ tends to dominate. The results also suggest strongly that the notable short-run fluctuations in the ratio are explained in terms of political displacement effects and economic crises considerations. Moreover, the contrasting political and economic climates of the countries in question serve to help highlight the role which political cultures play in the determination of public expenditure.     

Food consumption in urban China: an empirical analysis

This paper examines consumption patterns of urban households in China using aggregated household consumption data. A demand system comprising six commodities (rice,pork,vegetables,fish,eggs and fruits) is estimated using a two-stage budgeting procedure which incorporates an almost ideal deamnd system (AIDS) in each stage, Elasticity estimates from the system are plausible and consistent with other relevant studies. Results from this study strengthen the evidence of the emergence of a large Chinese market for non-stable food. The study provides rationale and basis for additional research into Chinese food consumption, especially processed food.
