Labor migration and the decoupling of the crop-livestock system in a rural mountainous area: Evidence from Chongqing,China

Massive out-migration of rural labor force brings both challenges and opportunities to crop-livestock integrated production system (crop-livestock system) in smallholder economy. Compared with previous researches that have paid major attention to the effect of labor migration on either crop production or livestock husbandry, this study considers the mediating role of crop production in predicting the effect of labor migration on livestock raising. Our econometric estimation based on a 2012 survey of 974 rural households in Chongqing, a mountainous region of China, showed the following. (1) The massive migration of rural labor force had led to significant increase in farmland abandonment and considerable changes in the pattern of livestock raising. (2) The livestock raising number per household began to differentiate, with the livestock system separating from the traditional crop-livestock system and becoming a specialized business. (3) In terms of the pathways through which rural labor migration exerts impact on livestock raising number, though the increased opportunity costs of rural labor greatly reduced farmers’ willingness to raise livestock, the decoupling of the crop-livestock system partly alleviated the declining trend in the livestock raising number because of the availability of household labor force freed from cropping via farmland abandonment. These findings have important policy implications for rural development and agricultural restructuring in mountainous areas of China, and provide references for other developing countries.     

When companies improve the sustainability of the natural environment: A study of large U.S. companies

In light of the call for companies to abandon current approaches to environmental management, this study adds to the environmental strategy literature and uses the evidence of competitive dynamics among companies to identify a mechanism by which companies invest in proactive environmental strategies and thereby improve the sustainability of the natural environment. An examination utilizing fixed effects regressions on a sample of large U.S.‐based companies reveal that even after controlling the number, environmental and financial performance of leading (environmental) companies, laggard (environmental) companies are more likely to invest in proactive environmental strategies when their leading peers display higher sustainability orientations. Neither the expectation of government regulation nor social movement pressure was found to be influential in this relationship. Therefore, the future dominance of companies' investments in the sustainability of the natural environment will be driven by companies themselves as long as competitive advantages are expected.     

基于经济阈值效应的地方政府举债压力弹性研究

地区所处经济阶段差异会使地方政府行为激励产生异质性,进而影响地区举债压力弹性。从经济阈值效应的独特视角,探究不同经济门槛区间压力波动引起的地方政府举债行为变化,利用举债压力弹性解释地方政府债务规模扩张成因。基于我国283个地级市数据,构建门槛面板模型对理论假设进行经验检验。研究发现:从低到高的经济阈值区间下地方政府举债压力弹性翻倍增长,尤其是在第三经济阈值区间,举债规模扩张呈现加速度特征;财政压力对地方政府举债的刺激作用,只有在第三经济阈值区间才会得以释放;“土地财政”的存在强化了地方政府举债对压力变化的敏感度,并助推了地方政府举债压力的弹性波动。经济处于发达阶段的地方政府的举债压力敏感度,显著高于处于欠发达阶段的地方政府,因此,高水平的城市举债压力弹性及其潜在的债务风险应成为下一步关注的焦点。     

The untold story of commodity futures in China

We investigate the behavior of commodity futures risk premia in China. In the presence of retail-dominance and barriers-to-entry, the term structure and momentum premia remain persistent, whereas hedging pressure, skewness, volatility, and liquidity premia are distorted by time-varying margins and strict position limits. Furthermore, open interest, currency, and inflation premia are sensitive to institutional settings. The observed premia cannot be attributed to common risks, sentiment, transactions costs, or data-snooping, but are related to liquidity, anchoring, and regulation-induced limits-to-arbitrage. We highlight the distinctive features of Chinese futures markets and assess the challenges posed to theories of commodity risk premia.     

Changing land use intensity in Europe – Recent processes in selected case studies

In recent decades the intensification of agricultural production in many European countries has been one of the key components of land-use change. The impact of agricultural intensification varies according to national and local contexts and a greater understanding of the drivers of intensification will help to mitigate against its negative impacts and harness potential benefits. This paper analyses changes in land use intensity in six case studies in Europe. A total of 437 landowners were interviewed and their responses were analysed in relation to changes in land use intensity and agricultural production between 2001 and 2011. In the case studies in Western and Eastern Europe we observed stabilisation during the last decade, and no clear tendency of increase or decrease of land use intensity. The use of fertilizers and pesticides seems to have decreased in our cases in Western Europe, which is contrary to trends in Eastern Europe. Agricultural production remained stable in almost all cases, except for an increase in Austria and Romania which may indicate that the farming efficiency has increased. A statistical analysis showed a division between study areas in Romania and Austria (increasing land use intensity) versus those in the Netherlands, Denmark and Greece (decreasing). In the Mediterranean cases we observe a process where agriculture is becoming increasingly marginalised, at the same time as changes in function with regard to urbanisation and recreational land uses have taken place. Logistic regression highlighted the importance of farm size and farmer type in understanding changes in land use intensity. The dominant pattern of stabilisation which has occurred over the past 10 years may also partly be a result of effective EU and national environmental and agricultural policies, which are increasingly concerned with improving environmental conditions in rural areas.     

Drivers of cropland abandonment in mountainous areas: A household decision model on farming scale in Southwest China

Cropland abandonment has emerged as a prevalent phenomenon in the mountainous areas of China. While there is a general understanding that this new trend is driven by the rising opportunity cost of rural labor, rigorous theoretical and empirical analyses are largely absent. This paper first develops a theoretical model to investigate household decisions on farming scale when off-farm labor market is accessible and there is heterogeneity of farmland productivity and distribution. The model is capable of explaining the hidden reasons of cropland abandonment in sloping and agriculturally less-favored locations. The model also unveils the impacts of heterogeneity of household labor on fallow decisions and the efficiency loss due to an imperfect labor market. The model is empirically tested by applying the Probit and Logit estimators to a unique household and land-plot survey dataset which contains 5258 plots of 599 rural households in Chongqing, a provincial level municipality, in Southwest China. The survey shows that more than 30% of the sample plots have been abandoned, mainly since 1992. The econometric results are consistent with our theoretical expectations. This work would help policy-makers and stakeholders to identify areas with a high probability of land abandonment and farming practice which is less sustainable in the mountainous areas.     

The joint effects of social identity and institutional pressures on audit quality: The case of the Chinese Audit Industry

This article examines how social identity links institutional pressures and audit quality. Combining institutional theory and social identity theory, we theoretically argue that the interaction between social and institutional forces shapes audit quality. Through an analysis of Chinese audit firms from 2000 to 2007, we show that isomorphic imitation has a more significant effect on firms belonging to the same-identity group than firms across cross-identity groups; foreign-affiliated audit firms are more willing to conform to normative pressure from professional networks than local firms; and foreign-affiliated firms are coerced to adapt to the local government’s expectation, particularly when they have a geographically concentrated customer base. We further reveal that a larger customer base attenuates within-identity group imitation but strengthens cross-identity group imitation. The results shed light on the role of social identity in shaping conformity in the audit industry, thus contributing to international convergence–divergence literature and institutional theory.     

Reconceptualizing cultural distance: The role of cultural experience reserve in cross-border acquisitions

Cultural distance is one of the most widely used distance construct in international business. However, scholars have long questioned the notion that cultural distance has a homogenous impact on organizational actions and performance. We redress this by examining how the relationship between cultural differences and deal abandonment in cross-border acquisitions is contingent on firm-level cultural experience reserve and industry affiliation. Drawing on the organizational learning theory and cultural friction perspective, we first propose that the cultural experience reserve of a focal firm mitigates the positive impact of cultural differences on cross-border deal abandonment. We then hypothesize that the firm's industry context affects the uncertainties associated with cultural differences. Our findings based on a sample of 197 Indian services sector firms support our theoretical predictions.

The Unintended Consequences of High Expectations and Pressure on New CEOs

We provide empirical tests of a general version of targeting theory that greater scrutiny could lead to executive abuses. Our results show that new CEOs under higher expectations or pressure are more likely to report meeting analyst forecasts; however, this apparent superior performance dissipates after excluding firms having characteristics synonymous with earnings manipulation. We find evidence that new CEOs under greater pressure are considerably more likely to engage in manipulation while the link between expectations and manipulation is much weaker. The results are strongest for new CEOs whose firms report meeting forecasts and do not “walk down” earnings estimates.
