Perspectives on determinants of social welfare: commentary

In this commentary we discuss and elaborate on a number of topics that have been raised in the articles in this issue. The first topic treated is causality. All scientists are aware of the difficulties of making causal inferences in non-experimental settings, and in many cases arguments are forwarded that support the causal interpretation of the reported relationships. Questions of bi-directional causality, nonlinear relationships and the importance of omitted variables are discussed, as is the supporting evidence that in some cases comes from experimental studies. The second topic is the level of analysis employed in the empirical analyses and the difficulty of interpreting findings at a different level of aggregation than the level applied in these analyses. In this context, the importance of applying a person-orientation is pointed out to ensure that the findings are interpretable at the level of the single individual. Even in individual-level analyses, this can be problematic if one relies on group statistics produced within a variable-oriented framework. The third topic concerns how to handle interactions and nonlinear relationships. The fourth topic concerns the importance of improving measurements so that a good correspondence is achieved between them and the theoretical conceptualisations. The fifth and last topic is concerned with the argument that different ways of investigating the generalisability of the results to different populations should be tried.     

Modernization,neo-liberal globalization,or variegated development: the Indian food system transformation in comparative perspective

This paper discusses the question of when generalizations risk compromising the utility and accuracy of a theory and seeks to show how a balance can be struck between generalized and context-specific analyses in disciplines like international sociology, political economy, and comparative politics. For this purpose, the paper reviews three theoretical approaches to agri-food system change, placed at different levels on the ladder of generality. It then considers these approaches in relation to India's changing agri-food system. Finally, the paper discusses the general and the particularistic features of the Indian case and examines their implications for theories relating to global governance and international political economy.     

SHADES OF BROWN AND GREEN: PARTY EFFECTS IN PROPORTIONAL ELECTION SYSTEMS

In proportional representation (PR) systems, political power is typically shared across several political parties. Many parties are small and focused on specific policies, such as environmental policy and immigration. Do these small parties matter for policy? I provide the first systematic evidence for this by developing the first regression discontinuity design tailored specifically for PR systems. With this method, which can be applied in all countries with PR systems, I estimate the causal effect of party representation on immigration policy, environmental policy and tax policy using data on Swedish municipalities. The results show that party representation has a large effect on the first two policies, but not on the tax policy.     

Generalised and Particularistic Thinking in Policy Analysis and Practice: The Case of Governance Reform in South Africa

This article is concerned with the relationship between generalised and particularistic knowledge in the context of policy‐making and policy analysis. It argues that it is problematic to assume that a reform model will generate similar outcomes across a wide variety of contexts. It presents a conceptual framework, including the concepts of transaction domain and domain consensus, that enables context‐sensitive analyses. The argument is exemplified by South Africa's introduction in the 1990s of an Integrated Development Planning model, based on British reform experience and various international public‐management models. With a case study of such planning in Lukhanji Municipality in the Eastern Cape Province, it illustrates how the conceptual framework may be used in policy research and analysis.     

Stochastic Monotonicity and Conditioning in the Limit

Suppose that {( X _n , Y _n )} is a sequence of pairs of cector-valued stochastic variables which converges weakly to ( X , Y ), and that { y _n } converges to y . Sufficient conditions for the conditional distribution of X _n given Y = y are given in terms of stochastic monotonicity. Conditions, which guarantee that also moments of the conditional distributions converge to the moments of the ones of the limit, are also derived.     

Twice chosen: Spouse matching and earnings among women in first and second unions

This study examines spouse matching for females in second order marriages or cohabitating relationships. It is based on detailed data from longitudinal Swedish population registers. We follow women who marry, divorce, and subsequently remarry compared to women who marry and remain married over the course of the study interval. The earnings of both groups, along with the earnings of their respective husbands, are modeled on the basis of data in the year prior to their marriages. From the regressions we obtain spouse-to-be pairs of earnings residuals and measure the correlation between spouses within each marital regime. Overall, we find significant positive residual correlations for both sample partitions. The correlation is smaller for the first of two marriages for women who divorce than for women who marry and remain married. For the second of successive marriages, however, the correlation is larger than that for women who marry but once. Also for twice-married women, we find evidence of matching between successive husbands. Women who marry men with unmeasured positive earnings capacities, in the event of divorce, tend to select and match in a similar fashion the second time around.
