A reconsideration of the link between vertical externality and managerial incentives

Previous research revealed that the strategic role of delegation contracts disappears if two quantity‐setting firms outsource input production to a monopolistic supplier. I show that this role is restored if the assumption of a downstream duopoly is relaxed. Thus, delegation contracts allow downstream profit‐maximizing owners to commit their firms to a behavior that differs from their preferences. This behavior varies nonmonotonically with the number of firms in the downstream market. Corresponding deviations from profit maximization are larger if the upstream monopolist makes a price precommitment. But little to no deviation occurs if the number of firms is large.     

Measuring progress in agricultural sustainability to support policy-making

The concept of sustainability is one of the forefront issues in discussions of the challenges facing global agriculture, given the mounting pressure to increase food production in both socially responsible and environmentally friendly ways. From the perspective of Irish agriculture, sustainable intensification is of particular relevance, given ambitious targets to increase milk production in the context of European Union (EU) milk quota removal in 2015. A series of farm-level sustainability indicators are developed here using the Teagasc National Farm Survey FADN (Farm Accountancy Data Network) data for Ireland from 2012. Three dimensions, reflecting the multifaceted nature of sustainability (environmental, economic and social) are considered. Given the environmental challenges inherent in the sustainable intensification of agriculture, it is encouraging to observe that the more intensive, top performing farms (in an economic sense) emit relatively less greenhouse gases when compared to their less intensive counterparts. Conversely, the better performing farms in economic terms tend to have a higher nitrogen surplus per hectare on average. This is consistent with their higher rates of production intensity, but poses a challenge in terms of sustainable intensification and expansion. That said this analysis demonstrates that the nitrogen use efficiency of milk production is positively correlated with economic performance, with more intensive farms producing relatively more milk per kilogram of nitrogen surplus. From the perspective of social sustainability, demographic traits also tend to be positively correlated with economic performance. Given a growing recognition of the need for interconnected policy in the area of sustainability, this research should help inform policy debates and provides a guide for the undertaking of similar assessments elsewhere.     

On the Reform of Rural Supply and Marketing Cooperatives in China

As a bridge between city and countryside, industry and agriculture, producer and consumer, Rural Supply and Marketing Cooperatives (RSMCs) play a key role in distributing commodities and purchasing rural products for some 800 million people in China. While overall national economic reform started in 1978, the reform of RSMCs began 4 years later in 1982 with greater emphasis on recovery rather than reform. This paper reviews the development of RSMCs, describes their operation and appraises the reform underway since 1982. It concludes with some policy suggestions relative to further reform of the RSMC system.     

Mean square error for the Leland–Lott hedging strategy: convex pay-offs

Leland’s approach to the hedging of derivatives under proportional transaction costs is based on an approximate replication of the European-type contingent claim V _T using the classical Black–Scholes formula with a suitably enlarged volatility. The formal mathematical framework is a scheme of series, i.e., a sequence of models with transaction cost coefficients k _n =k ₀ n ^−α , where α∈[0,1/2] and n is the number of portfolio revision dates. The enlarged volatility [^(s)]_n\widehat{\sigma}_{n} in general depends on n except for the case which was investigated in detail by Lott, to whom belongs the first rigorous result on convergence of the approximating portfolio value Vⁿ_TV^{n}_{T} to the pay-off V _T . In this paper, we consider only the Lott case α=1/2. We prove first, for an arbitrary pay-off V _T =G(S _T ) where G is a convex piecewise smooth function, that the mean square approximation error converges to zero with rate n ^−1/2 in L ² and find the first order term of the asymptotics. We are working in a setting with non-uniform revision intervals and establish the asymptotic expansion when the revision dates are t_iⁿ=g(i/n)t_{i}^{n}=g(i/n), where the strictly increasing scale function g:[0,1]→[0,1] and its inverse f are continuous with their first and second derivatives on the whole interval, or g(t)=1−(1−t) ^β , β≥1. We show that the sequence n^1/2(V_Tⁿ-V_T)n^{1/2}(V_{T}^{n}-V_{T}) converges in law to a random variable which is the terminal value of a component of a two-dimensional Markov diffusion process and calculate the limit. Our central result is a functional limit theorem for the discrepancy process.     

Value relevance and timeliness of transitional goodwill-impairment losses: Evidence from Canada

Focusing on transitional goodwill-impairment losses (losses) recorded by Canadian firms following the adoption of revised standards on purchased goodwill, we investigate the value relevance and timeliness of mandatory changes in accounting principles accounted for using the retroactive method. We find a negative relationship between reported losses and share price. Such a finding is consistent with investors perceiving losses as being sufficiently reliable measurements of a reduction in the value of goodwill to incorporate them in their valuation assessments. We find also that investors put a higher valuation weight on losses reported by firms that are expected to record a loss. In addition, we show that investors perceive that there are reduced opportunities for managerial discretion when there is a more effective audit committee. Finally, our results show that returns lead losses, i.e., that losses represent a catch-up adjustment to reflect the cumulative effect of using the impairment approach for the first time. Overall, our evidence supports U.S. standard setters' decision, through SFAS 154, to favour enhanced comparability and consistency over the potential costs of frequent restatements. Our results also show that fair-value measurements can be relevant even when the financial statement elements of interest are inherently bound to measurement error and subject to significant managerial discretion. They support the notion that reliability is about faithful representation, not precision.     

An investigation into the financial characteristics of dividend initiating firms

Dividend announcements are said to have an informational content concerning the value of the firm. Most studies on dividend announcements have involved models to predict change or to analyze that informational content. The purpose of this study is to establish the financial characteristics of firms that initiate or significantly increase dividends. One hundred firms were selected for study. Fifty of the firms had recently either initiated or significantly increased dividends; the other fifty were selected at random. Significant differences were found in the financial characteristics of the two groups. The results were generally consistent with previous studies and finance theory. There were however, two genuine surprises. The dividend initiating firms possessed lower levels of liquidity and activity than firms selected at random. This suggests that dividends may not be paid to dispose of excess cash, but to provide shareholders with some tangible reward in periods of low liquidity and little activity.     

Bayesian inference for the mover–stayer model in continuous time with an application to labour market transition data

This paper presents Bayesian inference procedures for the continuous time mover–stayer model applied to labour market transition data collected in discrete time. These methods allow us to derive the probability of embeddability of the discrete‐time modelling with the continuous‐time one. A special emphasis is put on two alternative procedures, namely the importance sampling algorithm and a new Gibbs sampling algorithm. Transition intensities, proportions of stayers and functions of these parameters are then estimated with the Gibbs sampling algorithm for individual transition data coming from the French Labour Force Surveys collected over the period 1986–2000.
