A recipe for success? Learning from the rapid adoption of improved chickpea varieties in Ethiopia

Many studies detail constraints deemed responsible for the limited adoption of new technologies among smallholder farmers in sub-Saharan Africa. By contrast, here we study the conditions that led to the remarkably fast spread of improved chickpea varieties in Ethiopia. Within just seven years, the adoption rate rose from 30 to 80% of the farmers. A combination of factors explains the rapid uptake. Their attraction lay in superior returns and disease resistance. Chickpea was already an important crop for rural households in the studied districts, for both cash income and consumption. Good market access and an easy accessibility of extension services advanced the adoption process. Thus, an attractive technology suitable for rural households in a conducive environment enabled adoption. Our findings prompt us to stress the importance of tailoring agricultural innovations to the realities and demands of rural households, and the need to design and deploy interventions on the basis of ex-ante knowledge on factors potentially determining their success or failure.     

The effect of minimum wages on employment in emerging economies: a survey and meta-analysis

Using both qualitative and quantitative (meta-analysis) methods, this paper reviews the growing evidence on the impact of minimum wages on employment in 14 major emerging economies (Argentina, Brazil, Chile, China, Colombia, India, Indonesia, Mexico, Poland, the Philippines, the Russian Federation, South Africa, Thailand and Turkey). Overall, minimum wages are found to have only a minimal impact on employment, and there is evidence of reporting bias towards statistically significant negative results. More vulnerable groups (e.g. youth and the low-skilled) are marginally more negatively affected, and there is some indication that higher minimum wages lead to more informal employment.     

DOES STUDENT WORK REALLY AFFECT EDUCATIONAL OUTCOMES? A REVIEW OF THE LITERATURE

We review the theories put forward, methodological approaches used and empirical conclusions found in the multidisciplinary literature on the relationship between student employment and educational outcomes. A systematic comparison of the empirical work yields new insights that go beyond the overall reported negative effect of more intensive working schemes and that are of high academic and policy relevance. One such insight uncovered by our review is that student employment seems to have a more adverse effect on educational decisions (continuing studies and enrolment in tertiary education) than on educational performance (test and exam scores).     

Technological change and the growing inequality in managerial compensation

Three of the most fundamental changes in US corporations since the early 1970s have been (1) the increased importance of organizational capital in production, (2) the increase in managerial income inequality and pay-performance sensitivity, and (3) the secular decrease in labor market reallocation. Our paper develops a simple explanation for these changes: a shift in the composition of productivity growth away from vintage-specific to general growth. This shift has stimulated the accumulation of organizational capital in existing firms and reduced the need for reallocating workers to new firms. We characterize the optimal managerial compensation contract when firms accumulate organizational capital but risk-averse managers cannot commit to staying with the firm. A calibrated version of the model reproduces the increase in managerial compensation inequality and the increased sensitivity of pay to performance in the data over the last three decades. This increased sensitivity of compensation to performance provides large, successful firms with the glue to retain their managers and the organizational capital embedded in them.     

Employment equity policy frames in the literature: ‘good practice’ versus ‘bad idea’

Work organisations considering policies against racial or ethnic discrimination and for recognising diversity can find many different and often conflicting recommendations in the literature, in particular regarding the aim of proportional representation of different ethnic groups. To better understand this controversy, this paper rigorously examines three key theories from a frame-critical and business ethics perspective. It introduces a fundamental threefold conceptualisation of ‘employment equity policy’ (EEP) as a catch-all term for related concepts such as ‘affirmative action’, ‘equal opportunities policy’ and ‘diversity management’, distinguishing between three different organisational goals: equal treatment, equal results and individual recognition. The analysis suggests that different authors emphasise some ‘facts’ rather than others and strategically interpret the limited available empirical research to support their policy positions, mixing both classical and newer ethical reasoning. In the ‘good practice’ frame, human resource management practitioners are urged to take ‘positive action’, to monitor the ethnic composition of the workforce and to formulate target figures to increase the representation of discriminated groups. In the opposing ‘bad idea’ frame, organisations are seriously advised against EEPs with ‘hard’ numerical goals: these policies supposedly are unnecessary and ineffective and have negative unintended consequences. The article draws implications from these findings for future research and practice in the field of EEPs.     

Does organizational ownership matter? Objectives of employees in public,nonprofit and for-profit nursing homes

Does organizational ownership matter for employees? We conducted a discrete choice experiment to reveal employees’ objectives in for-profit, nonprofit and governmental nursing homes. The results indicate that differences in objectives among nursing home staff are at least partially related to differences in ownership type. More specifically, we find that employees of public nursing homes are less extrinsically motivated than their for-profit and nonprofit counterparts. However, the results also show that employees of for-profit, nonprofit and governmental nursing homes are trading off output quality and output quantity differently, in line with the view that public providers of elderly care are pursuing a supplier-of-last-resort objective function.     

Finance and inequality: Channels and evidence

We provide a framework to interpret the recent literature on financial development and inequality. In many developing countries, access to funding and financial services by firms and households is still very skewed. Recent evidence suggests that poor access does not only reflect economic constraints but also barriers erected by insiders. Inequality affects the distribution of political influence, so financial regulation often is easily captured by established interests in unequal countries. Captured reforms deepen rather than broaden access, as small elites obtain most of the benefits while risks are socialized. Financial liberalization motivated to increase access may in practice increase fragility and inequality, and lead to political backlash against reforms. Thus financial reforms may succeed only if matched by a buildup in oversight institutions. Journal of Comparative Economics 35 (4) (2007) 748–773.
