Venture Capitalists, Business Angels, and Performance of Entrepreneurial IPOs in the UK and France

Abstract:  Using a unique sample of 444 entrepreneurial IPOs in the UK and France, this paper analyses the investment patterns and the stock-market performance effects of two types of early stage investors: venture capitalists (VCs) and business angels (BAs). Extending existing research, we identify important endogeneity and institutional effects. Our findings indicate that UK IPOs have a higher retained ownership and lower participation ratio by BAs, but a lower retained ownership and participation ratio by VCs than in France. BA and VC investments are substitutes, and they are endogenously determined by a number of firm- and founder-related factors, such as founder ownership and external board 'interlocks', and underwriter reputation. UK VCs are effective third-party certifying agents who reduce underpricing in UK IPOs, whereas in French IPOs they increase it by appearing to engage in grandstanding. This certification effect is more significant in UK IPOs involving both high VC and BA ownership. Finally, underpricing increases with VC participation ratio, where the higher exit of VCs seems to increase the risk premium required by outside investors, in particular in the UK.     

Finite additive utility representations for preferences over menus

I characterize a finite additive utility representation for preferences over menus. The numbers of both positive and negative components in this representation are expressed explicitly in terms of preference. These expressions can be used to characterize models of temptation, perfectionism, context effects, and other phenomena.     

The supply of and demand for accounting information

The article analyzes the use of accounting information in Russia. We assess reporting behaviour in the lending process for a sample of Russian companies in the years 1999–2004 and postulate that Russian companies manage their earnings in order to avoid showing losses when applying for bank financing. Once a credit has been granted, companies are predicted to manage earnings because of the bank's monitoring activities. By means of univariate and multivariate analysis we are able to attribute the discontinuity around a zero target in the earnings distribution with firms’ response to the banks’ assessment of accounting performance. This implies that financing considerations affect the reporting incentives of Russian companies.     

The effects of ownership concentration on investment and performance in privatized firms in Russia

This paper provides new survey evidence on effects of concentrated ownership on restructuring and performance in privatized firms in Russia. The major findings are that large‐block shareholding is negatively associated with the firm's investment and performance, and this relationship does not depend on the identity of controlling shareholders. These results are consistent with the assumption that when minority shareholders' rights are not adequately protected, the entrenched controlling shareholders may be engaged in extracting ‘control premium’ before pro rata distribution of dividends. The issues raised have relevance to other transitional economies where the privatization process has been followed by an increase in ownership concentration.

Patterns of Aging-Related Changes on the Way to 100

Abstract

The objective of this paper is to investigate dynamic properties of age trajectories of physiological indices and their effects on mortality risk and longevity using longitudinal data on more than 5,000 individuals collected in biennial examinations of the Framingham Heart Study (FHS) original cohort during about 50 subsequent years of follow-up. We first performed empirical analyses of the FHS longitudinal data. We evaluated average age trajectories of indices describing physiological states for different groups of individuals and established their connections with mortality risk. These indices include body mass index, diastolic blood pressure, pulse pressure, pulse rate, level of blood glucose, hematocrit, and serum cholesterol. To be able to investigate dynamic mechanisms responsible for changes in the aging human organisms using available longitudinal data, we further developed a stochastic process model of human mortality and aging, by including in it the notions of “physiological norms,” “allostatic adaptation and allostatic load,” “stress resistance,” and other characteristics associated with the internal process of aging and the effects of external disturbances. In this model, the persistent deviation of physiological indices from their normal values contributes to an increase in morbidity and mortality risks. We used the stochastic process model in the statistical analyses of longitudinal FHS data. We found that different indices have different average age patterns and different dynamic properties. We also found that age trajectories of long-lived individuals differ from those of the shorter-lived members of the FHS original cohort for both sexes. Using methods of statistical modeling, we evaluated “normal” age trajectories of physiological indices and the dynamic effects of allostatic adaptation. The model allows for evaluating average patterns of aging-related decline in stress resistance. This effect is captured by the narrowing of the U-shaped mortality risk (considered a function of physiological state) with age. We showed that individual indices and their rates of change with age, as well as other measures of individual variability, manifested during the life course are important contributors to mortality risks. The advantages and limitations of the approach are discussed.     

Asset market games of survival: a synthesis of evolutionary and dynamic games

The paper examines a game-theoretic model of a financial market in which asset prices are determined endogenously in terms of a short-run equilibrium. Investors use general, adaptive strategies (portfolio rules) depending on the exogenous states of the world and the observed history of the game. The main goal is to identify portfolio rules, allowing an investor to “survive,” i.e., to possess a positive, bounded away from zero, share of market wealth over an infinite time horizon. The model under consideration combines a strategic framework characteristic for stochastic dynamic games with an evolutionary solution concept (survival strategies), thereby linking two fundamental paradigms of game theory.     

Preparing Russian Small Innovative Enterprises for International Competitiveness: A Scoping Study

Russian small innovative enterprises (SIEs) are emerging as an important force behind the restructuring of the Russian economy and its industrial and commercial infrastructure. The research presented in this paper suggests that there are at least three categories of factors that impact the move of Russian SIEs into international markets: (i) macro-economic obstacles (ii) lacking managerial and business competencies and (iii) differences in culture and business practices. The first factor cannot be directly influenced by the individual SIE, while the latter two represent opportunities of a developmental nature. The work of this paper purports to lay the groundwork for more theoretical follow-up analyses.     

Insider-controlled Firms in Russia

Privatisation Vouchers in Russia were heavily invested in the holders' own firms. Using data from a recent survey, we show that insider control in firms privatised in 1992-4 through the voucher process (as distinct from the earlier leased buy-out method) is insecure and dependent on managers' support. For employees, investment in insider control appears to have been motivated by employment income insurance rather than expected excess returns on the equity. Managers are predominantly the same individuals as before privatisation and display considerable hostility to outside investors, probably because they fear dismissal should outsiders gain control. Despite insider control, firms are shedding labour quite rapidly through voluntary resignations. Employment dynamics appear to be unrelated to insider equity ownership.
