Optimal consumption policies in illiquid markets

We investigate optimal consumption policies in the liquidity risk model introduced by Pham and Tankov (Math. Finance 18:613–627, 2008). Our main result is to derive smoothness C ¹ results for the value functions of the portfolio/consumption choice problem. As an important consequence, we can prove the existence of the optimal control (portfolio/consumption strategy) which we characterize both in feedback form in terms of the derivatives of the value functions and as the solution of a second-order ODE. Finally, numerical illustrations of the behavior of optimal consumption strategies between two trading dates are given.     

Too Good to be True: Board Structural Independence as a Moderator of CEO Pay‐for‐Firm‐Performance

Whether voluntary or mandatory in nature, most recent corporate governance codes of best practice assume that board structural independence, and the application by boards of outcome‐based incentive plans, are important boundary conditions for the enforcement of Chief Executive Officer (CEO) pay‐for‐firm‐performance; that is, for optimal contracting between owners and executive agents. We test this logic on a large Australian sample using a system Generalized Method of Moments (GMM) approach to dynamic panel data estimation. We find that Australian boards exhibiting best practice structural arrangements – those chaired by non‐executives and dominated by non‐executive directors at the full board and compensation committee levels – are no more adept at enforcing CEO pay‐for‐firm‐performance than are executive‐dominated boards. These findings suggest that policy makers' faith in incentive plans and the moderating influence of structural independence per se may be misplaced. Our findings also hold significant implications for corporate governance theory. Specifically, the findings lend further support to a contingency‐based understanding of board composition, reward choice and monitoring; an approach integrating the insights afforded by behavioural approaches to Agency Theory and by social‐cognitive and institutional understandings of director outlook, decision‐making and behaviour.     

Personal Income Distribution and Market Structure

Income distribution affects market demand and its elasticity, and, as a consequence, the optimal behaviour of firms and market equilibrium. This paper focuses on the effects of income polarization, and presents a model where – for any unimodal density function describing income distribution of the consumers – income polarization leads to market concentration, i.e., to a smaller number of firms able to survive in the long run, provided that the firms' fixed costs are sufficiently low.     

Incorporating non-academics in academic spin-off entrepreneurial teams: the vertical diversity that can make the difference

To enhance the development of academic spin-offs, surrogate (external) entrepreneurs are often added to the entrepreneurial team comprising academics. Existing research focused on entrepreneurial team diversity (horizontal member differences) and has mixed results. Vertical member differences (i.e., inequality) between academics and non-academics are not addressed. However, strategic decision making is one of the main responsibilities of an entrepreneurial team. Decision-making power, as reflected in ownership, in particular, is thus of the essence. Based on a sample of 164 Italian academic spin-offs, this article investigates the impacts of both horizontal and vertical heterogeneity of entrepreneurial teams on the firms’ performance. The findings confirm that surrogate entrepreneurs generally make a positive contribution to academic spin-off performance but become counter-productive when their presence overpowers that of academics.

An empirical analysis of the relationship between university investments in Technology Transfer Offices and academic spin‐offs

The aim of this paper is to analyze the role of university Technology Transfer Offices (TTOs) in contributing to the creation and the performance of academic spin‐offs (ASOs). More specifically, it investigates the relationship between resources invested in TTOs in term of employees and the creation and growth of ASOs. The empirical analysis refers to Italy, where since 1999 academicians have been allowed to be actively involved in setting up companies for the ‘industrial use of research’. We used data on ASOs and resources invested by Italian universities in TTOs during the 2002–2011 period to investigate if and to what extent such investments contributed to the birth and growth of ASOs. We also controlled the results using information on university and on local context, in which university is located. The results of the empirical analysis show that in a first phase academicians reacted more promptly than universities to the opportunities offered by the new legislation, which may in part be due to the organizational rigidity that characterizes Public Administration in Italy. However, the empirical analysis also shows that after this initial phase the size of the TTOs (in terms of employees) has had a positive influence on the number of new ASOs (i.e. birth), but not on the performance of ASOs (i.e. growth), which is influenced by both long‐term investments in research (i.e. the quality of research results) and other variables linked to the regional and national contexts, such as the presence of incubators or the level of economic development. Our results regard a widely studied topic and should provide incremental findings for the community of entrepreneurship scholars and relevant implications for policy makers and TTO managers.     

Production smoothing, firms' heterogeneity, and financial constraints: evidence from a panel of UK firms

In this paper we provide an empirical analysis of heterogeneityin firms' inventory behavior, using a panel of UK manufacturingfirms. We first investigate how the relative variance of productionand sales differs across firms. We then use variants of thelinear quadratic inventory model in order to analyze potentialheterogeneity in firms' incentives to smooth production. Theresults suggest that incentives to smooth production are notprevalent This conclusion also holds when firms are partitionedaccording to whether they are more or leu likely to face finanrialconstraints.     

Internal financial constraints,external financial constraints,and investment choice: Evidence from a panel of UK firms

This paper uses a panel of 24,184 UK firms over the period 1993–2003 to study the extent to which the sensitivity of investment to cash flow differs at firms facing different degrees of internal and external financial constraints. Our results suggest that when the sample is split on the basis of the level of internal funds available to the firms, the relationship between investment and cash flow is U-shaped. On the other hand, the sensitivity of investment to cash flow tends to increase monotonically with the degree of external financial constraints faced by firms. Combining the internal with the external financial constraints, we find that the dependence of investment on cash flow is strongest for those externally financially constrained firms that have a relatively high level of internal funds.
