Testing for the Presence of Financial Constraints in US Agricultural Cooperatives: An Investment Behaviour Approach

This study examines the presence of financial constraints in US agricultural cooperatives. We test the cooperative capital constraint hypothesis with a panel data econometric analysis of agricultural cooperatives’ investment behaviour. Regression results suggest that agricultural cooperatives’ capital expenditures are significantly affected by the availability of internal funds. Results also indicate that the sensitivity of investment to cash flow is correlated with cooperative structural characteristics.

基于3E系统协调度的大兴安岭林区能源系统优化研究

在总结黑龙江大兴安岭林区能源-经济-环境(3E)系统发展现状的基础上,构建林区3E系统协调度评价指标体系,选用距离型协调度评价模型对其3E系统和任意两子系统之间的协调度进行定量分析,发现2004~2013年间林区的3E系统处于失调状态,而能源系统是制约3E系统发展的关键因素。因此,应该以提高能源系统发展水平为目标,从能源开发、消费的角度出发,构建以政府为主导、林区企业为载体、林区居民为受益者的能源系统优化体系。     

In search of conclusive evidence: How to test for adjustment to target capital structure

Simulation experiments show that both partial-adjustment and debt-equity choice models can generate spuriously significant estimates that are consistent with the hypothesis that firms have target debt ratios to which they periodically adjust. Regressions relying on full-sample fixed effects models of target leverage, in particular, produce results severely biased in favor of the target-adjustment hypothesis. Various target proxies and modifications to the standard methodologies are examined to identify partial-adjustment and debt-equity choice models that have power to reject the target-adjustment hypothesis. The resulting estimates of the speed of adjustment are in the range of five-eight percent per year.     

The informativeness and ability of independent multi-firm directors

Motivated by SEC regulations requiring a majority of independent directors on corporate boards, we examine director informativeness and ability by observing the trading performance of independent directors who serve on multiple boards. As a proxy for informativeness, we find positive trading performance relative to purchases and sales. More impressive, these performance opportunities appear to be available to market participants who observe directors' Form 4 trades. We do not find evidence that diversification motives or busyness affects director trading performance. On the other hand, we do find that audit and compensation committee memberships enhance director trading performance on the sales side but that committee membership does not affect the profitability of director purchases. In comparison, multi-firm directors out-perform single-firm directors and this performance differential seems to be more attributable to superior ability than to better information.     

Long term changes in voting power and control structure following the unification of dual class shares

We study the effects of a regulatory change that induced the unification of most dual class shares in Israel in the 1990s. Specifically, we follow the evolution of ownership structure in a sample of 80 companies that unified their dual-class shares, and compare it with a control sample of firms that maintained their dual share structure at least until 2000. Our main findings are as follows. First, controlling shareholders offset the dilution of voting rights they incurred upon unification by: 1) increasing their holdings prior to the unification (ex-ante preparation), and 2) by buying shares afterwards; by the end of the sample period their voting power was only marginally lower than in the control sample. This offsetting result suggests that marginal voting rights may be important to controlling shareholders even beyond the 50% threshold. Second, share unifications were not associated with much change in the identity of controlling shareholders. Third, the proportion of firms affiliated with pyramidal business groups in the sample of unifying firms was lower than in the population of listed firms as a whole and not different from that in the control sample, suggesting that pyramidal ownership structures did not replace dual class shares. Finally, unifying firms did not exhibit a substantial improvement in their performance and valuation in comparison with the control sample.     

Does shareholder approval requirement of equity compensation plans matter?

This paper studies the impact of the 2003 SEC Regulation requiring shareholder approval of all equity-based executive compensation plans on executive compensation policies and practices at S&P 500 firms. Following the 2003 Regulation, firms with shareholder approved equity plans in place or those with strong performance, while not those with non-approved plans or weak performance, increase their equity compensation proposal submission activity. The quality of equity compensation proposals improves in the after-regulation period, and shareholders exhibit greater scrutiny and monitoring of executive compensation through increased voting rights. We find a decline in the equity pay component while an increase in the cash component of total executive compensation after the 2003 Regulation and also provide evidence that the 2003 Regulation contributes to this change in compensation structure.     

Fundamentals,Misvaluation, and Business Investment

Does stock market misvaluation affect business fixed investment? To answer this question, we provide evidence based on U.S. firm‐level panel data. We examine the orthogonality conditions for the investment Q and Euler equations, and our qualitative tests reject the null hypothesis that investment is unaffected by misvaluation (this result is not driven exclusively by the late 1990s). To measure the quantitative effects on investment, we introduce a measure of misvaluation into standard investment equations. Our estimates imply that a one‐standard‐deviation increase in misvaluation increases investment between 20% and 60% relative to the mean level of investment in the sample.     

Convergence of Real Capital Market Interest Rates—Evidence from Inflation Indexed Bonds

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.     

Confidence building on Euro convergence: Evidence from currency options

We study the evolution of investor confidence in 1992-1998 over the chance of individual currencies to converge to the Euro, using data on currency option prices. Convergence risk, which may reflect uncertainty over policy commitment as well as exogenous fundamentals, induces a level of implied volatility in excess of actual volatility. This volatility wedge should gradually decrease as confidence grows over time as convergence policy is maintained, and the risk of a reversal is progressively resolved. Empirically, we indeed find a positive volatility wedge which declines over time only for currencies involved in the Euro convergence process. The wedge and other convergence risk measures are correlated with both exogenous fundamentals and proxies for policy commitment uncertainty. We also find that the wedge responds to policy shocks in an asymmetric fashion, suggesting that policy risk is resolved at different rates after negative and positive shocks. Finally, we estimate a regime-switching model of convergence uncertainty, using data on interest rates, currency rates, and currency option prices. The results confirm the time-varying and asymmetric nature of convergence risk, and indicate that investors demand a risk premium for convergence risk.
