Unpacking the impact of innovation ambidexterity on export performance: Microfoundations and infrastructure investment

When designing and managing routines for their innovation activities firms often face a challenge. Either they can concentrate their efforts on one approach i.e. exploring new ideas or exploiting its existing capabilities, or they can try to do both, i.e. becoming ambidextrous. In this paper, we aim to explore first the effect of exploration, exploitation and ambidexterity on export performance and second the moderating role of investment in infrastructure. Using firm-level data from the UK’s innovation survey (CIS) we find that both exploration and exploitation improve export performance. We also find that investment in infrastructure weakens this relationship. Counterintuitively, we find that ambidexterity has a negative effect on export performance, and that it is negatively moderated by investment in infrastructure. We use microfoundations arguments (the routines firms employ and the actions taken by individuals and groups within them to shape their exporting capabilities) to explain how efforts to achieve ambidexterity can improve export performance.     

Long‐term Performance of Greek IPOs

We analyse the long‐run performance of 254 Greek IPOs that were listed during the period 1994–2002, computing buy‐and‐hold abnormal returns (BHAR) and cumulative abnormal returns (CAR) over 36 months of secondary market performance. The empirical results differ from international evidence and reveal long‐term overperformance that continues for a substantial interval after listing. Measuring these returns in calendar time, we find statistical significance with several of the benchmarks employed. We also find that long‐term overperformance is a feature of the mass of IPOs conducted during a pronounced IPO wave. Cross‐sectional regressions of long‐run performance disclose several significant factors. The study demonstrates that although Greek IPOs overperform the market for a longer period, underperformance eventually emerges, in line with much international evidence. Our interpretation is that the persistence of overperformance over a significant interval is due to excessive supply of issues during the ‘hot IPO period’. Results associated with pricing during the ‘hot IPO period’ indicate positive short‐ (1‐year), medium‐ (2‐year) and negative long‐term (3‐year) performance.     

Political geography and stock returns: The value and risk implications of proximity to political power

We show that political geography has a pervasive effect on the cross-section of stock returns. We collect election results over a 40-year period and use a political alignment index (PAI) of each state's leading politicians with the ruling (presidential) party to proxy for local firms’ proximity to political power. Firms whose headquarters are located in high PAI states outperform those located in low PAI states, both in terms of raw returns, and on a risk-adjusted basis. Overall, although we cannot rule out indirect political connectedness advantages as an explanation of the PAI effect, our results are consistent with the notion that proximity to political power has stock return implications because it reflects firms’ exposure to policy risk.     

Is British output growth related to its uncertainty? Evidence using eight centuries of data

We examine the empirical relationship between output variability and output growth for Britain using data for eight centuries covering the 1270 to 2014 period. Drawing on the economic history literature, we split the full sample period into four subperiods and use GARCH models to measure output growth uncertainty and estimate its effect on average growth. Within each sub-sample, we allow output growth to depend on the state of the system, for example 2-regime switching model would switch between high-growth and low-growth regimes. We find that the effect of uncertainty on growth differs depending on the existing growth regime. Low-growth regimes are associated with a negative effect of uncertainty on growth, and medium or high-growth regimes are associated with a positive effect. These findings are consistent across the four states of economic development. Our results indicate why the empirical literature to date has found mixed results when examining the effect of uncertainty on growth.     

The restricted convex risk measures in actuarial solvency

In this article, we propose a class of convex risk measures defined on appropriate wedges of a space of financial positions which denote the cumulative surplus variables created by undertaking risks by either an insurance or a reinsurance company. The form of the wedge which is the domain of such a risk measure expresses the form of the company, and it is a subspace in the case of reinsurance companies and a cone in the case of the insurance companies. The value of such a risk measure on an insurance position denotes the capital that the corresponding company has to receive or to keep in advance so that it will not be exposed to risk due to this position. We prove some dual representation and continuity results being similar to the unrestricted case. Finally, we contribute to a decision theory related to the choice of a numeraire asset when the space in which the positions lie in is reflexive.     

Europeanisation under authoritarian rule: Greek business and the hoped-for transition to electoral politics, 1967–1974

ABSTRACT

The article addresses the domestic impact of the freezing of the Greek association with the European Economic Community (EEC) on business–government relations during the colonels’ dictatorship in Greece (1967–1974). Focusing on the Federation of Greek Industries (SEV), the author argues that in the face of the Europeanisation of Greek industry, Greek business embarked upon a strategy prioritising liberalisation as a means towards rapprochement with the EEC. But this strategy was not part of a pro-democracy agenda. On the contrary, seeking a viable political regime and future accession to the EEC, SEV supported an abortive authoritarian transition to electoral politics in 1973.     

Firm Size and the Nature of International Relationships: The Case of Globally Integrated Small Firms

During the past quarter of a century or so there was a marked increase in the number of studies exploring the internationalization of the small firm. The basic premise of this body of literature was that the size of the firm mattered in the process of internationalization. Research in this area focused heavily on types of forward integration (particularly exporting), and examined a handful of key research questions: which national markets shall a small firm enter, how, and when, as well as the impact of internationalization on business performance. Rather unexpectedly, to date there have been no studies exploring the impact of firm size on the nature of relationships created by small firms. This paper aspires to address this gap in the literature by focusing upon globally integrated small enterprises. Drawing on the evidence of 755 firms in five EU countries the paper argues that there are no profound differences in the nature of international relationships created by globally integrated small firms in comparison to their large‐scale counterparts. More importantly, however, the paper suggests that power asymmetry and mutuality may coexist in international relationship, and small firms may often occupy positions of power in global commodity chains.     

The effects of market structure on industry growth: Rivalrous non-excludable capital

We analyze imperfect competition in dynamic environments where firms use rivalrous but non-excludable industry-specific capital that is provided exogenously. Capital depreciation depends on utilization, so firms influence the evolution of the capital equipment through more or less intensive supply in the final-goods market. Strategic incentives stem from, (i) a dynamic externality, arising due to the non-excludability of the capital stock, leading firms to compete for its use (rivalry), and, (ii) a market externality, leading to the classic Cournot-type supply competition. Comparing alternative market structures, we isolate the effect of these externalities on strategies and industry growth.     

Do Analysts Influence Corporate Financing and Investment?

We examine whether abnormal analyst coverage influences the external financing and investment decisions of the firm. Controlling for self-selection bias in analysts' excessive coverage, we find that firms with high (low) analyst coverage consistently engage in higher (lower) external financing than do their industry peers of similar size. Our evidence also demonstrates that firms with excessive analyst coverage overinvest and realize lower future returns than do firms with low analyst coverage. Our findings are consistent with the hypothesis that analysts favor the coverage of firms that have the potential to engage in profitable investment-banking business.
