The formation of public utility holding companies and their subsequent diversification activity

This paper examines the stock market reaction to announcements that utilities are converting to utility holding companies. There are negative abnormal returns associated with these announcements. Holding companies permit these utilities to diversify beyond the utility industry, and the announcements of their formation may signal the market of their intentions to diversify. The negative abnormal returns associated with these announcements and the negative abnormal returns associated with subsequent announcements of acquisitions are consistent with other research showing that diversifying bidders lose more (or gain less) than non-diversifying bidders.     

Financial and economic determinants of firm default

This paper investigates the relevance of financial and economic variables as determinants of firm default. Our analysis covers a large sample of medium-sized limited liability firms. Since default might lead, through bankruptcy or radical restructuring, to firm’s exit, our work also relates to previous contributions on industrial demography. Using non parametric tests we assess to what extent defaulting firms differ from the non-defaulting group. Bootstrap probit regressions confirm that economic variables, in addition to standard financial indicators, play both a long and short term effect. Our findings are robust with respect to the inclusion of Distance to Default and risk ratings among the regressors.     

The determinants of research and development intensity in the UK

The primary purpose of this paper is to discover whether research and development expenditures are related to firm size, market structure and technological influences in the UK. After providing a preliminary analysis of R & D activity, the paper tackles the problem of the rather limited data set. Two approaches are adopted: first, analysing part of the relationship using a broadly based sample, and second, providing data on a more narrowly based sample over three years. The results suggest that firm size and concentration have virtually no influence on R & D intensity in the UK among firms with R & D programmes.     

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.     

Conditional correlations in the returns on oil companies stock prices and their determinants

The identification of the forces that drive stock returns and the dynamics of their associated volatilities is a major concern in empirical economics and finance. This analysis is extremely important for determining optimal hedging strategies. This paper investigates the stock prices’ returns and their financial risk factors for several integrated oil companies, namely Bp (BP), Chevron-Texaco (CVX), Eni (ENI), Exxon-Mobil (XOM), Royal Dutch (RD) and Total-Fina Elf (TFE). We measure the actual co-risk in stock returns and their determinants “within” and “between” the different oil companies, using multivariate cointegration techniques in modelling the conditional mean, as well as multivariate GARCH models for the conditional variances. The distinguishing features of this paper are: (i) focus on the determinants of the market value of each company using the cointegrated VAR/VECM methodology; (ii) specification of the conditional variances of VECM residuals with the Constant Conditional Correlation (CCC) multivariate GARCH model of Bollerslev [(1990) Review of Economics and Statistics 72:498–505] and the Dynamic Conditional Correlation (DCC) multivariate GARCH model of Engle [(2002) Journal of Business and Economic Statistics 20:339–350]; (iii) discussion of the performance of optimal hedge ratios calculated with the DCC estimates. The “within” and “between” DCC indicate time-varying interdependence between stock return volatilities and their determinants. Moreover, DCC models are shown to produce more accurate hedging strategies.     

Benchmarking and firm heterogeneity: a latent class analysis for German electricity distribution companies

In January 2009, the German Federal Network Agency introduced incentive regulation for the electricity distribution sector based on results obtained from econometric and nonparametric benchmarking analysis. One main problem for the regulator in assigning the relative efficiency scores is unobserved firm-specific factors such as network and technological differences. Comparing the efficiency of different firms usually assumes that they operate under the same production technology, thus unobserved factors might be inappropriately understood as inefficiency. To avoid this type of misspecification in regulatory practice, estimation is carried out in two stages: in the first stage observations are classified into two categories according to the size of the network operators. Then separate analyses are conducted for each subgroup. This article shows how to disentangle the heterogeneity from inefficiency in one step, using a latent class model for stochastic frontiers. As the classification is not based on a priori sample separation criteria it delivers more robust, statistically significant, and testable results. Against this background, we analyze the level of technical efficiency of different subgroups from a sample of 200 regional and local German electricity distribution companies for a balanced panel data set (2001–2005). Testing the hypothesis if larger distributors operate under a different technology than smaller ones, we assess if a single step latent class model provides new insights to the use of benchmarking approaches within the incentive regulation schemes.     

Stimulating different types of eco-innovation in the UK: Government policies and firm motivations

In this paper, we adopt a recent OECD framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco-innovations that range on a spectrum of lower to higher technological and environmental impacts: End-of-Pipeline Pollution Control Technologies, Integrated Cleaner Production Technologies and Environmental R&D. Using a novel firm-level dataset from a DEFRA survey, we estimate a Tobit model, which provides empirical evidence showing that these eco-innovations are motivated by different external policy tools and internal firm specific factors. Our findings indicate that End of Pipeline Technologies and Integrated Cleaner Production Technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the End-of-Pipeline technologies and Environmental R&D. Interestingly, alongside government induced regulations, we find that market factors, mainly motivated by cost savings, are effective in driving Environmental R&D. Finally, ISO14001 certification is effective in strengthening the positive impact of environmental management systems on both End-of-Pipeline technologies and Environmental R&D while CSR policies have no significant impact on motivating any of the eco-innovations.     

A simple theory and evidence on the determinants of firm R&D

This paper derives a simple, but informative, model of firm R&D to figure out key factors that determine firm R&D effort. The model suggests a demand-pull, technology-push theory of R&D by showing that a firm's profit-maximizing R&D expenditure is determined jointly by both demand-side factors and technology-side factors. The former includes demand size (firm sales) and consumer preference over quality and price and the latter includes R&D cost structure or the production-cost effect of product R&D and firm-specific technological competence. In addition, the model shows that other things being equal, the stock of exogenous technological knowledge, including the firm's previously accumulated technological knowledge, relevant to current R&D which is negatively related with current R&D effort. An empirical analysis of firm R&D intensities and technological capabilities of more than 1600 firms in nine industries across six countries provides supportive evidence for the theory. Further, the theory implies that R&D intensity or the R&D-to-sales ratio is independent of firm size unless firm size affects technological competence and that given consumer preference and R&D cost structure facing all firms in the same industry, the distribution of firm-specific technological competence among firms determines the distribution of firm R&D intensities within the industry.     

Non-linearity in the determinants of capital structure: evidence from UK firms

We demonstrate that, by exploiting more fully the distribution of leverage, conditional quantile regression methods yield new insights into the choice of leverage ratio. For UK listed companies we find that not only is the estimated effect of the explanatory variables different at different quantiles of the distribution, but also that the effect of a variable changes sign between low leveraged and high leveraged firms.      

Some empirical evidence on the determinants of incomes policies in the UK

A model is proposed in which incomes policy is the endogenous variable and is explained by political and economic variables. The empirical results show that the party in power, inflation, wage change and unemployment effect the chances of an incomes policy.     

Collaboration and firm size: some evidence from the UK defence industry

This paper presents evidence on the relationship between collaboration and firm size derived from an empirical study of the UK defence industry. The results indicate that size has a positive impact on collaboration and, in particular, with the propensity to collaborate with overseas firms. However, size has no impact on the propensity to collaborate with UK partners. This lends support to theories which emphasize the resource constraints facing small firms in developing international collaboration. There is a need for a policy debate concerning mechanisms to promote collaboration to assist small firms to realise the benefits of international collaboration.     

Relationship between initiative risk management and firm value: evidence from Chinese financial listed companies

This study considers 189 Chinese financial listed companies between 2009 and 2013 as research samples to establish indicators for evaluating the initiative risk management behaviour of financial enterprises. This work further examines the relationship between initiative risk management and firm value. Results show that financial enterprises could effectively increase firm value by taking initiative risk management measures, such as setting up departments or positions that specialize in risk management, using financial derivative instruments or engaging popular international accounting firms as audit institutions. Moreover, results reveal that the permeability of initiative risk management has an unstable effect on firm value, that is, a nonlinear relationship exists between the permeability of initiative risk management and firm value.     

Small,young, and exporters: New evidence on the determinants of firm growth

This work investigates how the export status of the firm influences the patterns of employment growth at different age classes. We address this research question resorting to a novel set of data that links together the universe of Italian firms and detailed data on export transactions. We find that the positive relationship between export status and growth declines with firm age. Further, we also find that, even when accounting for the role of age, the negative size-growth relationship does not disappear, contrary to some recent evidence. These results suggest a positive signaling role of the export status that is stronger for young exporters or born globals. Exploiting the product-country level dimension of the customs data, we also provide, for the first time, evidence on differences in exchange rates pass-through between young and experienced exporters. In particular, we find that early exporters appear to be better equipped than established firms to face exchange rates variations as their exports decrease less following a currency appreciation.     

The firm in early Modern China

The Chinese shareholding entity had a long history supported by cultural and legal practices pre-dating the introduction of European business forms in China. In the absence of codified or systematic precedent-based private law, a culture in which contract was deeply embedded in daily practice and the state enforced private agreements sustained a growing commercial sector. Kinship practices were adapted to the needs of a merchant community seeking ways to pool capital and sustain firm longevity. These institutional developments help to explain Chinese adaptability to Western practices and the paradoxical persistence of Chinese practices after the promulgation of a Western-style company law.     

An empirical study of the determinants of UK oil and gas voluntary disclosures

Significant oil and gas firm market value is derived from their physical reserve quantum, assets which are not recorded on their statements of financial position. This article provides empirical evidence regarding voluntary disclosure of such reserves in line with the previously unresearched UK sector with regard to its unique reporting guidelines. The study considers both the reporting of the reserve quantum and the quality of that reporting. This article seeks to inform the International Accounting Standards Board’s (IASB’s) on-going consideration of mineral resource reporting. Listed companies are considered to evidence forms of reserve disclosure with a logistical regression approach applied to measure determinants of reporting. The risk associated with mineral reporting reserves is hypothesized as the key disclosure driver whilst controlling other relevant variables. The majority of firms disclosed reserve quantities in some form but only a minority disclosed in line with recommended practice, disclosure quality being more variable between companies. The findings indicate that a voluntary disclosure approach is ineffective, partially explained by agency related behaviour. Risk, proxied by the stage of production, drives reserve disclosure showing that producer firms are more likely to disclose reserve quantum balances and of a significantly higher quality.     

The multifactor Illyrian firm revisited

Comparative static results for the single output, multifactor, short-run dividend-maximizing firm are derived and classified. Two determinate situations are identified; first, if the production technology is Hicksian-normal and homogeneous, both Ward perversions (negative responses of both labor and output to an increased product price) follow and, second, if labor is inferior, a positively sloped supply curve but a perverse labor response result. The possibility of labor responding positively to a price increase is demonstrated in which case the supply curve will be positively sloped. A distinction between labor-intensive and materials-intensive technologies indicates that the latter is more likely to exhibit Ward perversion. Implications for empirical work are discussed.
