Inequality and Participative Democracy: A Self-Reinforcing Mechanism

During the last three decades, a notable increase in economic inequality is observed, accompanied by a decline in people's engagement in politics and electoral participation. This is an unsatisfactory phenomenon as it undermines the legitimacy of democratic representation. This negative association is produced by a complex salient mechanism. This study aims at investigating this issue. Using data from a panel of 28 OECD and European countries, this paper identifies a two-way causal relationship between inequality and political participation. The results show that greater income inequality alienates and discourages people from engaging with common affairs, thus leading to lower political participation. Yet, lower electoral participation leads towards a less equitable distribution of income. Hence, this study reveals a self-reinforcing mechanism where the unequal distribution of income leads to political exclusion, which in turn leads to more inequality.     

Capitalisation of R&D and the informativeness of stock prices: Pre- and post-IFRS evidence

We examine whether requiring (IFRS) versus allowing (UK GAAP) conditional capitalisation of development expenditure affects the extent to which capitalisation conveys more information about future earnings, relative to expensing. We show that capitalisation results in current returns incorporating more future earnings information than expensing under UK GAAP but not under IFRS. i.e., the amount of information incorporated into market prices of capitalisers is the same as that from firms expensing R&D under IFRS. This result holds irrespective of a firm’s earnings management incentives or strength of corporate governance for the period under IFRS. We argue that this is because investors experience greater uncertainty regarding the realisation of future economic benefits associated with the development costs capitalised in the post-IFRS period. Consistent with this, we do find a positive association between capitalised R&D and future earnings variability in the post-IFRS period only, as well as short-term positive abnormal returns for capitalisers relative to expensers in the pre-IFRS period only. Overall, these findings suggest that when moving away from a standard that offers an overt option to capitalise or expense, capitalisation comes with greater uncertainty, which is resolved only in the long term.     

Heterogeneity of Long‐run Technical Efficiency of German Dairy Farms: A Bayesian Approach*

In parametric efficiency studies, two alternative approaches exist to provide an estimate of the long‐run efficiency of firms: the dynamic stochastic frontier model and the generalised true random‐effects model. We extend the former in order to allow for heterogeneity in the long‐run technical efficiency of firms. This model is based on potential differences in firm‐specific characteristics and in firms’ inefficiency persistence. The model is applied to an unbalanced micro‐panel of German dairy farms over the period 1999 to 2009. Estimation of long‐run technical efficiency and inefficiency persistence is based on an output distance function representation of the production technology and estimated in a Bayesian framework. The results suggest that heterogeneity in long‐run technical efficiency of farms is mostly attributed to discrepancies in farm‐specific factors rather than differences in farms’ inefficiency persistence. Farm size is positively related to long‐run technical efficiency while subsidies exert a negative effect on the long‐run technical efficiency of farms. Inefficiency persistence is found to be very high, but heterogeneity in this persistence is low.

Integrated reporting decision usefulness: Mainstream equity market views

The International Integrated Reporting (<IR>) Framework (2013) identified providers of financial capital as its primary users. This research provides evidence from 22 mainstream equity market actors, employed by global investment houses, regarding the decision usefulness of and resistances to <IR>, as a reporting framework. Despite institutional-level support for <IR>, the interviews reveal that its usefulness to fund managers and equity analysts is low. Concerns are evident over the Framework design and its relevance to more structural issues pertaining to equity market culture. The implication of this is that <IR> may become a reporting fad, not embedded into mainstream investment thinking.     

Hedge fund pricing and model uncertainty

This article uses Bayesian model averaging to study model uncertainty in hedge fund pricing. We show how to incorporate heteroscedasticity, thus, we develop a framework that jointly accounts for model uncertainty and heteroscedasticity. Relevant risk factors are identified and compared with those selected through standard model selection techniques. The analysis reveals that a model selection strategy that accounts for model uncertainty in hedge fund pricing regressions can be superior in estimation/inference. We explore potential impacts of our approach by analysing individual funds and show that they can be economically important.     

Liquidity uncertainty and intermediation

The paper performs a welfare comparison between demand deposit and equity contracts in the presence of intrinsic aggregate uncertainty. In this framework, the welfare dominance of deposit contracts emerges under corner preferences. It is shown that aggregate uncertainty creates high price volatility of ex-dividend equity claims traded in a secondary market and the resulting consumption allocations offer less risk-sharing opportunities to risk-averse consumers than tailor-made deposit contracts. The contingency of early payoffs on depositors’ withdrawal order reinforces the welfare performance of deposit contracts, whereas costly liquidation of productive long-term investments deteriorates their welfare performance relative to equity contracts.     

Dynamics of Firm Profitability and Growth: Do Knowledge-Intensive (Business) Services Persistently Outperform?

This paper explores the persistence of profitability and growth for firms operating in the Greek service sector, paying special attention to knowledge-intensive services (KIS) and knowledge-intensive business services (KIBS). The generalized method of moments is used on a rich panel of firms over a recent nine-year period. Quantile regressions are complementarily applied for KIS and KIBS industries. The key results from both growth and profit dynamics suggest that firms in KIS and KIBS industries persistently outperform firms in less knowledge-intensive service industries, pointing to strategic advantages of the former. Importantly, KIS and KIBS seem to be able to sustain their growth and profitability persistent trends even in times of crisis. Further insight into these issues is provided by the quantile analysis, the exploration of the profitability and growth inter-linkages, and the investigation of differences among various size groups in KIS and KIBS.     

The Bierens test for certain nonstationary models

We adapt the Bierens (1990) test to the I-regular models of Park and Phillips (2001). Bierens (1990) defines the test hypothesis in terms of a conditional moment condition. Under the null hypothesis, the moment condition holds with probability one. The probability measure used is that induced by the variables in the model, that are assumed to be strictly stationary. Our framework is nonstationary and this approach is not always applicable. We show that the Lebesgue measure can be used instead in a meaningful way. The resultant test is consistent against all I-regular alternatives.     

Access to private equity and real firm activity: Evidence from PIPEs

We study how access to private equity financing affects real firm activities using a broad panel of publicly traded U.S. firms that raise external equity through private placements (PIPEs) between 1995 and 2008. The public firms relying on PIPEs are generally small, high-tech firms that cannot finance investment internally and likely face severe external financing constraints; PIPEs are by far the most important source of finance for these firms. We show that firms use PIPE inflows to maintain extremely high R&D investment ratios and to build substantial cash reserves. We also use GMM techniques that control for firm-specific effects and the endogeneity of the decision to raise private equity and find that PIPE funding has a substantial impact on corporate investment in cash reserves and R&D, and a smaller but significant impact on investment in non-cash working capital, but little impact on fixed investment or acquisitions. Our estimates indicate that R&D investment initially increases by $0.20–$0.25 for each dollar of private equity flowing into the firm, and that PIPE funds initially invested in cash ultimately go to R&D. These findings offer direct evidence that access to private equity finance has an important effect on the key input that drives innovation at the firm- and economy-wide levels.
