Agriculture looks for ‘shoes that fit’: The production responsibility system and its implications

by the end of 1981 problems clearly recognized within the communes included low productivity, the failure to accumulate funds for modern inputs, inefficient and corrupt cadres, hidden unemployment, inability to stimulate growth in other than major crops and disappointingly low levels of peasant incomes in many counties. In north China, peasants in 1980 began to divide up the collective fields on communes into smaller plots for cultivation by households and labour groups. Since then the face of China has been altered — physically, politically and organizationally — by the creation of the ‘responsibility system’ largely outside party control and influence. ‘Document 75’ of September 1980 sanctioning some form of ‘production responsibility system’ was itself overtaken by events, as a bewildering variety of forms emerged, swamping the cadres. Practice was rapidly expanding beyond the theoretical discussions, or pronouncements of officials like Du Runsheng The paper describes each of the many forms of contracting between peasant groups and the State now current in China, with estimates of the relative proportions of the accounting units involved in each type (Table 3). New contradictions are already emerging in the changed rural set-up, partly because farm management problems bear similarities to those that confronted the open-field strip farming of the European Manor, while the incentive to have more hands on family farms contradicts official Chinese population policy.     

Managing disabilities in an integrated health environment: the experience of Aetna

Disability-related outlays are increasing at a rate well above the medical inflation rate. This article discusses the experience of one company in its attempt to manage these skyrocketing costs, by developing a new program that integrates health and related benefits by combining the medical and human resources interventions into a unified program. The authors discuss the initiation, development and progress of the program, concluding with measured results revealing reduced lost work time, improved employee health and productivity, and reduced disability costs.     

Are there economies of scale in the demand for money by firms? Some panel data estimates

We estimate elasticities of scale in the demand for money by firms using firm level panel data from Spain, the UK, and the US. This elasticity is one for Spain and the UK but smaller for the US. We find that the errors in the money demand equations contain two terms that are correlated with sales. Firstly, a permanent firm effect that captures differences in technological sophistication. Secondly, a measurement error in sales, which becomes relevant when relying on changes in sales to account for fixed effects. Failure to control for these correlated unobservable terms results in important biases in the estimated sales elasticities.     

Low-frequency robust cointegration testing

Standard inference in cointegrating models is fragile because it relies on an assumption of an I(1)$I\left(1\right)$ model for the common stochastic trends, which may not accurately describe the data’s persistence. This paper considers low-frequency tests about cointegrating vectors under a range of restrictions on the common stochastic trends. We quantify how much power can potentially be gained by exploiting correct restrictions, as well as the magnitude of size distortions if such restrictions are imposed erroneously. A simple test motivated by the analysis in Wright (2000) is developed and shown to be approximately optimal for inference about a single cointegrating vector in the unrestricted stochastic trend model.     

Profit Related Pay and the U.K. Small Firm Labour Market

This paper critically examines the relevance of profit related pay (PRP) for the U.K. small firm sector. Since 1986, the U.K. government has actively encouraged PRP, which attracts generous tax breaks, because it believed that PRP would make pay more flexible downwards and would significantly improve employee identification, morale and productivity. An analysis of the theoretical arguments and the assumptions made regarding the nature of the U.K. small firm sector that underlay these claims suggests, however, that the likelihood of achieving either of these alleged benefits is small. An appraisal of the available empirical evidence on the practical implementation and operation of PRP schemes suggests that the tax relief simply encourages firms to introduce cosmetic schemes that have no appreciable impact upon the behaviour of either firms or employees. Moreover, the experience of some firms that adopted PRP schemes indicates that, far from increasing morale and productivity, PRP often creates new tensions and conflict between owners and employees. These and other unintended consequences illustrate the inherent difficulties of government attempts to use the tax system to alter the behaviour of agents engaged in a wide variety of complex and very heterogeneous bargaining situations.     

Deciphering Tax Avoidance: Evidence from Credit Rating Disagreements

This study investigates the role of tax avoidance in the credit‐rating process and whether differences exist in how rating agencies account for the risk relevance of tax avoidance. Using a sample of initial credit ratings assigned to public debt issuances during 1994–2013, our evidence is consistent with Moody's Investors Service and Standard & Poor's assessing the costs and benefits associated with tax avoidance differently from one another, resulting in more frequent and pronounced rating agency disagreement. Rating agency disagreement over tax avoidance is most evident when it is accompanied by relatively high levels of uncertain tax positions, foreign activities, research and development activities, or tax footnote opacity. We also find evidence that decreases (increases) in tax avoidance or tax footnote disclosure opacity are positively (negatively) associated with the convergence of split ratings. This suggests that firms can exacerbate or mitigate rating agency disagreement subsequent to bond issuance. Our study complements prior research by examining why sophisticated information intermediaries disagree about the risk relevance of tax avoidance. It also sheds light on how firms can influence rating agencies’ understanding of tax avoidance.     

A socio-technical framework for assessing the viability of carbon capture and storage technology

Carbon capture and storage (CCS) is seen as a key technology to tackle climate change. The principal idea of CCS is to remove carbon from the flue gases arising from burning fuels for electricity generation or industrial applications and to store the carbon in geological formations to prevent it from entering the atmosphere. Policy makers in several countries are supportive of the technology, but a number of uncertainties hamper its further development and deployment. The paper makes three related contributions to the literatures on socio-technical systems and technology assessment: 1) It systematically develops an interdisciplinary framework to assess the main uncertainties of CCS innovation. These include technical, economic, financial, political and societal issues. 2) It identifies important linkages between these uncertainties. 3) It develops qualitative and quantitative indicators for assessing these uncertainties. This framework aims to help decision making on CCS by private and public actors and is designed to be applicable to a wider range of low carbon technologies. The paper is based on a systematic review of the social science literature on CCS and on insights from innovation studies, as well as on interviews about assessment of new technologies with experts from a range of organisations and sectors.     

Spatial variations in the relationship between economic diversity and stability

Using US county-level data, we explore how economic diversity influenced economic stability over the period of the Great Recession. We find that higher diversity is associated with greater stability, but there are distinct spatial patterns and the relationship does not hold for much of the central part of the US.
