How does firm diversification impact innovation?

This study sheds light on the relationship between business diversification and innovation. A diversification strategy is both a driver of sunk costs and strategic slack. Strategic slack is a valuable reserve of knowledge, usable to foster innovation. Using linear models, we explore the interplay between research and development (R&D) and organisational slack in large and diversified companies listed on the Euronext 100 Index. We consider the diversification pattern over time, and its interactions with the following three categories: sunk costs, slack resources, and R&D. The results show an antithetic effect of diversification and slack on R&D expenditures. In contrast to unabsorbed and potential slack, diversification and sunk costs hinder innovation. However, diversification is a huge source of strategic slack and, thus, has a positive effect on innovation, indirectly.     

How does knowledge network affect a firm’s explorative innovation? The contingent role of R&D collaborations

Innovation is a process of knowledge recombination [Fleming, L. 2001. “Recombinant Uncertainty in Technological Search.” Management Science 47: 119 p]. Extant literature highlights the importance of a firm’s knowledge base for innovation, while little is known about the structure of a firm’s knowledge base and how it affects the firm’s explorative innovation. Based upon the perspective of network analysis, we portray a firm’s knowledge base as an intra-organisational knowledge network and examine the effects of two structural features of the network – density and centralisation – on the firms’ exploratory innovation. Using a manual collected dataset of 738 Chinese automobile manufacturers, we find that a firm explores fewer new knowledge elements when the firm holds a dense knowledge network or a centralised knowledge network. More importantly, with the increase of a firm’s R&D collaborations with external actors, the negative effect of density is mitigated while the negative effect of centralisation is reinforced. Both theoretical and practical implications are discussed.     

How does anti-corruption affect firm labour inputs? Evidence from a quasi-natural experiment in China

This study investigates the impact of anti-corruption on firm labour inputs. Using the province-by-province rollout of the central inspection team campaign in China, we find that the labour intensity rises by 9% in the firms located in the provinces inspected by the central inspection teams. Moreover, firms with low corruption are more susceptible to the policy shock.     

Simultaneous board and CEO diversity: does it increase firm value?

There remain open questions regarding whether board of director ethnic and gender diversity increases or decreases firm value. Additionally, prior research has yet to examine the value effects of a diverse board in the presence of a gender/ethnic minority CEO. Using the KLD social ratings database, we examine 13?000 firm-years and provide robust evidence that board diversity increases firm value. However, we also show that any value added via board diversity is nullified when a diverse board operates in the presence of a female and/or minority CEO. Results suggest that a significant portion of the value in board diversity may come from gender/ethnic differences between the board members and the CEO. One implication of our study is that when hiring a CEO or electing directors relative gender/ethnic make-up is important.     

How do different motives for R&D cooperation affect firm performance? – An analysis based on Swiss micro data

The starting point of our analysis is the empirical fact that firms pursue different goals when getting engaged in R&D collaborations, often more than one goal at the same time. Given that firms are driven by different motives for R&D cooperation, the aim of this article is to investigate the differences related to different motives with respect to the impact of R&D cooperation on firm innovativeness and firm productivity. Not only R&D cooperation in general but also cooperation driven by each of the seven motives considered in this paper correlate positively with the sales share of innovative products. With respect to innovativeness, the characterization of cooperation by the driving motive did not add much more than could be gained through the overall variable ‘R&D cooperation yes/no’. Technology-motivated collaborative activities show a weaker tendency to positive direct effects on productivity than cost-motivated cooperation. In this case, the distinction of several cooperation motives yields some additional insights as compared to the overall cooperation variable. On the whole, distinguishing various cooperation motives appears to be fruitful because it allows more differentiated insights that would remain hidden behind the overall variable “R&D cooperation yes/no”.     

How does bargaining power affect remittances?

This paper examines the factors affecting the amount of remittances by migrants to their home countries, in a context of a family bargaining model. Spanish data does not show the same clear relationship between remittances and migrant income that is captured in the theoretical literature and certain empirical papers. Family bargaining models emerge as a useful framework within which to study remittances, and bargaining power is a key element in determining the level of such remittances. As a consequence of the consideration of bargaining power, the effect of income levels on remittances emerges as non-monotonic.     

How does female labor force participation impact on housing values?

Female labor force participation (FLFP) and household wealth are two main topics of interests to economists for long time. The objective of this study is to investigate the response of housing values, household wealth, to female labor force participation using panel level data in the U.S. states. We develop static and dynamic estimation models using state-level data in the U.S. from 2005 to 2013. The results show the FLFP rate and per capita income have a strong positive effect on housing values, while the number of units per capita has a negative effect on housing values in the state. We find that a 10% increase in FLFP will result in an increase of about 12.5% on housing values. Additionally, increasing per capita income by 10% on average will cause housing values to rise by 9%, however, a 10% rise in the number of units per capita will decrease housing values by 30%. The results assist economists and policy makers in assessing policies to optimize decisions in labor market and housing market.     

How does leverage in stock market influence the margin of stock index futures?

In this article, we propose a margin-setting model under the assumption of extreme stock price changes. Specifically, extreme stock price changes are caused by the positive feedback effect of leverage and market impact. By introducing these factors into the futures price changes through a cost-of-carry model for setting the margin of stock index futures, we find that leverage and market impact in stock market are positively correlated with the margin.     

How does petty corruption affect tax morale in Sub-Saharan Africa?

Revenues from taxation gain in importance to finance economic development in Sub-Saharan Africa. One obstacle to enhancing the willingness to remit taxes can be the extortion of bribes by public officials. Using micro-level data from the Afrobarometer, we show that petty corruption erodes tax morale. The effect on tax morale is more severe in countries and regions where fewer people are affected by petty corruption and becomes insignificant if extortion of bribes is particularly prevalent. Differing levels of civic participation and potential access to tax funded services are also found to induce heterogeneous reactions to corruption experience. Applying a mediation analysis, we demonstrate that petty corruption not only has a direct effect on tax morale but also diminishes confidence in tax authorities and therefore affects tax morale indirectly. The harmful effects of corruption experience, however, operate mainly through a generally lowered inclination to uphold high levels of tax morale.     

How does organizational structure affect executive compensation?

Does the rise of the CFO as the second-ranked executive increase the status of the CEO? We find that, as a CFO becomes #2, a CEO receives higher pay in relative terms compared with other top executives. This result corresponds to the literature on span-of-control of executives in top management team.     

How does the internet affect migration decisions?

This article provides new evidence on the impact of the internet on migration decisions. I find that an increase in internet adoption among migrant-sending countries reduces the stock of migrants from these locations. The results are robust to a number of specifications, including an instrumental variable approach that addresses the endogeneity of internet adoption. The findings suggest that the internet may weaken the importance of push factors in the decision to migrate, and that these effects outweigh declines in mobility costs.     

How does informal employment impact income inequality?

This study investigates how informal employment impacts total income inequality in urban China. Finite mixture methodology is employed to examine the segments that exist in the informal labour market, and the Theil index (T0) is used to break down total income inequality according to different subsamples. We found that the two-segment model (upper-tier and lower-tier) best describes the structure of the informal labour market in urban China and that the upper-tier segment contributes most to the total income inequality.     

How does legislative behavior change when the country becomes democratic? The case of South Korea

The Political Legislation Cycle theory predicts a peak of legislative production in the pre-electoral period, when legislators focus on voters’ welfare to be reelected. This paper verifies the theory on South Korean legislative production (1948–2016); it is the first test of the theory in a country undergoing a process of democratization, thus providing evidence relevant also for the conditional political cycles literature. Two insofar untested hypotheses are verified: 1) peaks of legislative production should increase with the degree of democracy; 2) as the party system and the mechanisms of legislative checks and balances develop, the PLC should become more evident in bills of legislative rather than executive’s initiative. A hurdle model estimated on both laws of parliamentary proposal and of government assignment lends empirical support to both hypotheses, with the noticeable feature that PLC in Korea appear more in the form of an upward trend than of pre-electoral peaks.     

Going offshore or better staying in? Spatial relocation strategies and their impact on firm innovativeness

We analyse the short- to mid-run effects of spatial relocation strategies on firm innovativeness and productivity growth. Using conditional difference-in-difference estimation with multiple treatments, we find for a sample of German firms in 1999–2013 that offshoring has a statistically significant negative impact on the firms’ innovation activity and productivity growth vis-à-vis nonrelocating comparison firms. In contrast, we find a positive link between domestic relocation activities and the firms’ propensity to introduce a product innovation. Firms should thus carefully account for potentially distorting performance effects when deciding about the spatial scale of relocation strategies in the short to mid-run.     

How does a mixed ownership firm license a patent?

This paper demonstrates that a cost disadvantaged innovator increasingly relies on licensing with a fixed fee as its public ownership share grows. Moreover, when the innovation is drastic, a cost disadvantaged innovator frequently licenses by fixed fee when it has a public share even as a fully private firm will never use a fixed fee. As the fixed fee improves welfare, these results suggest that the licensing method of a partial public firm helps correct the market failure of imperfect competition.     

How does violence affect exporters? Evidence from political strikes in Bangladesh

Using novel daily data, we examine the impact of political violence on firm‐level export activity. Our data cover the universe of political strikes and export transactions in Bangladesh during 2010–2013 and allow us to examine the effects of these strikes at a highly granular level. We first show that multiday political strikes lower the likelihood that a firm will export by 6.30 percentage points. We then examine whether these disruptions result in adverse effects on export prices. Given that this violence creates greater risk of missed shipments, importers may respond by demanding lower prices as compensation. We provide the first evidence of such adverse price effects of political violence. Our results suggest that during July to December, 2013, when there was a multiday political strike every 5 days, the prices of time‐sensitive Bangladeshi products declined by 1.59%.     

How does anti-corruption campaign affect the labour income share in China?

Based on the difference-in-difference (DID) methodology, this paper empirically investigates the impact of the current anti-corruption campaign on the share of labour income in China. Using a firm-level data on Chinese corporations listed on Shanghai and Shenzhen Stock Exchanges from 2009 to 2015, we find that the campaign contributes to the rise in the labour income share, while there is considerable heterogeneity. The magnitude of the effect depends on firm’s ownership and market power. This paper advances the existing studies examining the nexus between corruption and income distribution from a novel perspective.     

Why does bad news increase volatility and decrease leverage?

A recent literature shows how an increase in volatility reduces leverage. However, in order to explain pro-cyclical leverage it assumes that bad news increases volatility, that is, it assumes an inverse relationship between first and second moments of asset returns. This paper suggests a reason why bad news is more often than not associated with higher future volatility. We show that, in a model with endogenous leverage and heterogeneous beliefs, agents have the incentive to invest mostly in technologies that become more volatile in bad times. Agents choose these technologies because they can be leveraged more during normal times. Together with the existing literature this explains pro-cyclical leverage. The result also gives a rationale to the pattern of volatility smiles observed in stock options since 1987. Finally, the paper presents for the first time a dynamic model in which an asset is endogenously traded simultaneously at different margin requirements in equilibrium.     

How does financial development influence the impact of remittances on growth volatility?

This paper empirically examines how financial development influences the impact of remittances on GDP growth volatility. This empirical study is conducted using the panel smooth transition regression (PSTR) approach. The results show that the impact of remittances on GDP growth volatility is nonlinear and changes over time and across countries in function of financial development. More precisely, a high level of financial development helps remittances to have a high stabilizing impact. Therefore, public authorities in remittance recipient countries might implement policies that promote the financial sector in order to allow a high stabilizing impact of remittances.     

How does a pay-as-you-go system affect asset returns and the equity premium?

When applying a differences-in-differences approach, equity returns and the equity premium are both estimated to be more than four percentage points higher after the introduction of a pay-as-you-go (PAYGO) system. In a realistically calibrated model, the PAYGO system is also found to increase the returns and the premium, although the effects are smaller than in the data. Intuitively, the system lowers asset prices, which in turn increases the importance of dividend risk. Since only equity is subject to dividend risk, equity returns become more volatile relative to bond returns.
