Will African Agriculture Survive Climate Change?

Measurement of the likely magnitude of the economic impact ofclimate change on African agriculture has been a challenge.Using data from a survey of more than 9,000 farmers across 11African countries, a cross-sectional approach estimates howfarm net revenues are affected by climate change compared withcurrent mean temperature. Revenues fall with warming for drylandcrops (temperature elasticity of –1.9) and livestock (–5.4),whereas revenues rise for irrigated crops (elasticity of 0.5),which are located in relatively cool parts of Africa and arebuffered by irrigation from the effects of warming. At first,warming has little net aggregate effect as the gains for irrigatedcrops offset the losses for dryland crops and livestock. Warming,however, will likely reduce dryland farm income immedia-tely.The final effects will also depend on changes in precipitation,because revenues from all farm types increase with precipitation.Because irrigated farms are less sensitive to climate, wherewater is available, irrigation is a practical adaptation toclimate change in Africa.     

Debt, managerial compensation and learning

Using a dynamic model with uncertainty and asymmetric information, we study the impact of debt and bankruptcy on managerial compensation and learning. In this model, compensation has two roles to play—providing incentives to the manager and learning about his type. We show that debt, through bankruptcy, acts as a substitute of compensation in both dimensions and derive conditions under which debt lowers average compensation, pay-performance sensitivity and increases learning. We also examine the choice of debt and show that firm value can be increased due to debt's effect on managerial compensation, abstracting from other costs and benefits of debt. Finally, we conduct comparative statics with respect to the underlying parameters.     

The path-to-profitability of Internet IPO firms

Extant empirical evidence indicates that the proportion of firms going public prior to achieving profitability has been increasing over time. This phenomenon is largely driven by an increase in the proportion of technology firms going public. Since there is considerable uncertainty regarding the long-term economic viability of these firms at the time of going public, identifying factors that influence their ability to attain key post-IPO milestones such as achieving profitability represents an important area of research. We employ a theoretical framework built around agency and signaling considerations to identify factors that influence the probability and timing of post-IPO profitability of Internet IPO firms. We estimate Cox Proportional Hazards models to test whether factors identified by our theoretical framework significantly impact the probability of post-IPO profitability as a function of time. We find that the probability of post-IPO profitability increases with pre-IPO investor demand and change in ownership at the IPO of the top officers and directors. On the other hand, the probability of post-IPO profitability decreases with the venture capital participation, proportion of outsiders on the board, and pre-market valuation uncertainty.     

Venture capitalist participation and the post-issue operating performance of IPO firms

Previous studies have identified the value-added potential of venture capitalist monitoring in the initial public offering (IPO) market. We test this proposition by comparing the post-issue operating performance of venture capitalist-backed IPOs with a matched sample of non-venture capitalist-backed IPOs. We find that venture capitalist-backed IPO firms exhibit relatively superior post-issue operating performance compared to non-venture capital-backed IPO firms. Further, the market appears to recognize the value of monitoring by venture capitalists as reflected in the higher valuations at the time of the IPO. Finally, we find that proxies for the quality of venture capitalist monitoring are positively related to post-issue operating performance.     

Trade Union Responses to zero hours work in Ireland

This paper examines the strategies adopted by Irish unions in responding to zero hours work in four sectors. It concludes that rather than adopting either a passive or a uniform approach, unions have pragmatically varied their strategies to curtail zero‐hours work through actively combining both bargaining and regulatory approaches.

Commonality in liquidity and multilateral trading facilities

We use the introduction of two multilateral trading facilities (MTFs) to examine the impact of market fragmentation on commonality in liquidity. We find that the introduction of MTFs following the Markets in Financial Instruments Directive increases the comovement of stocks’ liquidity with MTF liquidity, while the comovement with the home market liquidity generally decreases. We also find that the higher the MTF trading volume or the number of MTFs trading a stock, the stronger the effect. Further, we find that the commonality in liquidity remains unchanged for a matched control sample of stocks that do not trade on MTFs.
