Measuring human development: a stochastic dominance approach

We consider a weighting scheme that yields a best-case scenario for measured human development such as the official equally-weighted Human Development Index (HDI) using an approach that relies on consistent tests for stochastic dominance efficiency. We compare the official equally-weighted HDI to all possible indices constructed from a set of individual components to obtain the most optimistic scenario for development. In the best-case scenario index education is weighted considerably more than the other two components, per capita income and life expectancy, relative to the weight that it gets in the official equally-weighted index. It also turns out that the improvement in the official HDI is mainly driven by improvements over time in the education index, the component moving fastest relative to its targets, when compared with per capita income and life expectancy. We find that the best-case scenario hybrid index leads to a marked improvement of measured development over time when compared with the official equally-weighted HDI.     

The effect of regulatory scrutiny: Asymmetric cost pass-through in power wholesale and its end

We find an asymmetric pass-through of European emission allowance (EUA) prices to wholesale electricity prices in Germany and show that this asymmetry disappeared in response to a report on investigations by the competition authority. The asymmetric pricing pattern, however, was not detected at the time of the report, nor had it been part of the investigations. Our results therefore provide evidence for the deterring effect of regulatory monitoring on firms which exhibit non-competitive pricing behavior. We do not find any asymmetric pass-through of EUA prices in recent years. Several robustness checks support our results.     

The effect of entry on R&D networks

We investigate the effect of potential entry on the formation and stability of R&D networks considering farsighted firms. The presence of a potential entrant often alters the incentives of incumbents to collaborate. Incumbent firms may form an otherwise undesirable collaboration to deter entry of a new firm. Moreover, an incumbent may refrain from establishing an otherwise desirable collaboration, expecting to form a more profitable link with the entrant. Finally, potential entry may lead an inefficient incumbent to exit the market. Welfare analysis shows market and social incentives to be often misaligned. We propose a subsidy scheme that encourages welfare‐improving entry.     

The Role of Institutional Uncertainty for Social Sustainability of Companies and Supply Chains

Global sourcing largely occurs from so-called emerging markets and developing economies (EMDEs). In these contexts, substantial leverage effects for sustainability in supply chains (SCs) can be expected by reducing adverse impacts on society and minimising related risks. For this ethical end, an adequate understanding of the respective sourcing contexts is fundamental. This case study of South Africa’s (SA) mining sector uses institutional theory and the notion of institutional uncertainty to empirically analyse the challenges associated with establishing social sustainability. The case study research is informed by 39 semi-structured interviews with top management representatives and various state and non-state decision makers in SA. Our findings suggest that (social) sustainability in the institutional field is mainly shaped by the Social and Labour Plan institution, induced by state actors and mining companies’ practices. However, four weakening factors were identified that adversely affect this regulative institution, drive institutional uncertainty and allow for mining companies’ gradual decoupling. Contrastingly, complementing pressures of non-state actors limit institutional uncertainty and push toward mainstreaming the stipulations of the institution. This study contributes to the business ethics literature by providing an in-depth exploration of institutional uncertainty’s drivers and barriers within an upstream SC setting and shedding light on multiple actors’ interplay and relevance in sector-wide sustainability. The findings are condensed into three main propositions as well as an analytical framework as a basis for follow-up research. This case study helps practitioners understand and manage complexity that results from actor plurality and institutional uncertainty in EMDEs.

     

Misreporting of Government Transfers: How Important Are Survey Design and Geography?

Recent studies linking household surveys to administrative records reveal high rates of misreporting of program receipt. We use the FoodAPS survey to examine whether the findings of these studies of general household surveys using one or two states generalize to a survey with a narrow focus and across many states. First, we study how reporting errors differ from other surveys. We find a lower rate of false negatives (failures to report true receipt) in FoodAPS, likely partly due to the shorter recall period of FoodAPS. Misreporting varies with household characteristics and between interviewers. Second, we examine geographic heterogeneity in survey error to assess whether we can extrapolate from linked data from a few states. We find systematic differences between states in unconditional error rates but no evidence of substantial differences conditional on common covariates. Thus, extrapolating error rates across states may yield more accurate receipt estimates than uncorrected survey estimates.     

The evolution of stock market efficiency in the US: a non-Bayesian time-varying model approach

A non-Bayesian time-varying model is developed by introducing the concept of the degree of market efficiency that varies over time. This model may be seen as a reflection of the idea that continuous technological progress alters the trading environment over time. With new methodologies and a new measure of the degree of market efficiency, we examine whether the US stock market evolves over time. In particular, a time-varying autoregressive (TV-AR) model is employed. Our main findings are: (i) the US stock market has evolved over time and the degree of market efficiency has cyclical fluctuations with a considerably long periodicity, from 30 to 40 years; and (ii) the US stock market has been efficient with the exception of four times in our sample period: during the long recession of 1873–1879; the recession of 1902–1904; the New Deal era; and the recession of 1957–1958 and soon after it. It is then shown that our results are partly consistent with the view of behavioural finance.     

Analysis of rural development policy networks in Greece: Is LEADER really different?

This paper presents an application of quantitative network analysis. It examines rural development projects with respect to their structural and politico-administrative dimensions, including power relations, conflicts, multifunctionality and intersectorality. The network structures and relations of comparable IPRD and LEADER projects are analyzed. The LEADER project network is shown to be less hierarchical than the IPRD project network, although the LEADER network is not characterized by significantly simpler procedures or clearer policy content than the IPRD network. Information and contact are significantly greater, and conflict density is significantly lower in the LEADER network. Administrative intersectorality is higher in the IPRD project, while the multidisciplinarity and the multifunctionality are higher in the LEADER project. However, the LEADER project is not perceived as delivering its objectives to a greater extent than the IPRD project. The implications for process-oriented evaluation are discussed.     

International stock market efficiency: a non-Bayesian time-varying model approach

This article develops a non-Bayesian methodology to analyse the time-varying structure of international linkages and market efficiency in G7 countries. We consider a non-Bayesian time-varying vector autoregressive (TV-VAR) model, and apply it to estimate the joint degree of market efficiency in the sense of Fama (1970, 1991). Our empirical results provide a new perspective that the international linkages and market efficiency change over time and that their behaviours correspond well to historical events of the international financial system.
