Grid Parity and Cost Reduction Incentives for “Green Producers” in Electricity Markets

In an electricity market, a feed-in tariff promotes attainment of a so-called “green quota” through a system of subsidies designed to ensure renewable energy investors a “normal rate-of-return”. However, the subsidies should track technological advances closely with the expectation that they will be phased out when the renewable technology reaches an appropriate “maturity threshold” (i.e., grid parity). Grid parity is typically defined as the point where the levelized cost of electricity equals the price of purchasing electricity from the grid. However, it has been recognized that this definition of grid parity is flawed due to the intermittent nature of many renewable resources. We propose a definition which allows us to distinguish between grid parity and least-cost grid parity. We demonstrate that under a green quota and an emissions cap, welfare may be higher if the policy maker forgoes least-cost grid parity and phases out the feed-in system sooner rather than later. We show that while green producer cost reduction incentives under the feed-in tariff are perverse, they can be restored by offering a “menu” of values of the policy variables and allowing full discretion in terms of the decision to engage in cost-padding, pure waste, etc.     

Election systems,the “beauty premium” in politics,and the beauty of dissent

We ask three questions. First, do election systems differ in how they translate physical attractiveness of candidates into electoral success? Second, do political parties strategically exploit the “beauty premium” when deciding on which candidates to nominate, and, third, do elected MPs use their beauty premium to reap some independence from their party? Using the German election system that combines first-past-the-post election with party-list proportional representation, our results show that plurality elections provide more scope for translating physical attractiveness into electoral success than proportional representation. Whether political parties strategically use the beauty premium to optimize their electoral objectives is less clear. Physically attractive MPs, however, allow themselves to dissent more often, i.e. they vote more often against the party line than their less attractive peers.     

Full price competition and Dupuit's defense of the long-and-short-haul “discrimination”

Condemnation of the long-and-short-haul discrimination has been nearly ubiquitous in the literature on economic theory and transportation. However, the French economist Dupuit developed a case against all transport regulation by relating it to a defense of the practice of place discrimination before the middle of the nineteenth century. He did so, moreover, within an early elaboration of a full price explanation of competitive functioning. This paper analyzes the idea in Dupuit's context and argues that this so-called form of price discrimination is actually an efficient and necessary form of the competitive process.     

Value,sign, and social structure: the ‘game’ metaphor and modern social science

This exploratory paper, part of continued work on the history of game theory, seeks to illustrate certain links between von Neumann's theory of games and contemporaneous ideas in other fields. In particular, we claim that the emergence of the analytical metaphor of the ‘game’ in economics can be viewed as part of a general reconceptualization of theory in a range of disciplines. That methodological reconstitution may be described as the emergence of a Structuralist view, an approach to theorizing which treated its object – be that a text, a kinship arrangement, or an economy – as a self-contained system, with its own internal logic, subject to its own ‘laws’. In particular, individual texts, or observed social and economic arrangements, are now viewed as variations on an underlying logical theme, on a structural invariant. The latter is to be uncovered, in the case of linguistics, through the analysis of phonemes; in kinship analysis, through the rules governing the exchange of women because of the incest taboo; in von Neumann and Morgensterns game theory, through the possibilities for equilibrium coalition formation, based on the stable set. There thus emerged a tendency, across the intellectual spectrum, towards seeing things in combinatorialterms. Theoretical coherence was to be found in examining how objects ‘held together’ rather than analysing where they ‘came from’: nineteenth-century concerns with history, evolution and individual psychology give way to a distinctly modern emphasis on synchronic, formal structure, on analogical reasoning. Atomism gave way to holism, and formal elegance superceded immediate empirical content. Recourse to the metaphor of the ‘game’ was constitutive of this shift, which we examine by referring to Saussures General Course in Linguistics, to Formalism in mathematics and literary analysis, to Lévi-Strauss's analysis of kinship and myth, and to von Neumann and Morgenstern's Theory of Games and Economic Behaviour.     

Value-added exports and the skill premium: Evidence from China’s international and regional production networks

The present study examines the impact of value-added exports on the skill premium in a large developing country. We distinguish two margins of value-added trade: direct exporting measures the economic activities of de jure exporters, while indirect exporting reflects the induced demand for suppliers for exporters. We integrate China’1s internal and external production networks and draw empirical evidence from both population and economic censuses. Our findings show that aggregate value-added export intensity is associated with a higher skill premium, but it encompasses two contrasting effects: the direct exporting channel increases the skill premium, whereas the indirect channel decreases it. The latter channel has been neglected in existing published studies, which can lead to an overestimation of the positive relationship between exports and inequality in the South. We discuss the possible mechanisms and important implications.     

“Crime” in the lab-detecting social interaction

According to the standard economic perspective, criminal activities vary with the ‘price’ of crime, which depends on the severity of punishment and the detection probability. An alternative view claims that crime is also influenced by social interaction phenomena, such as ‘peer pressure’ or ‘neighbourhood effects’. Detecting social interaction in the field is fraught with difficulties, however. In this paper, we argue that given its extensive control possibilities, experiments are well suited to show the potential existence of social interaction effects. We present an experimental study where people can engage in ‘criminal’ activities. We find support for the importance of social interaction: On average subjects steal the more, the more others steal. This behaviour can be interpreted in terms of reciprocity.     

Europe,the Green Line and the Issue of the Israeli-Palestinian Border: Closing the Gap between Discourse and Practice?

The article analyses how the Europeans (meaning European states and the EC/EU) have progressively turned a discourse about the Israeli-Palestinian border into a foreign policy practice. While much of the literature highlights the existence of a ‘gap between discourse and practice’ when it comes to Europeans’ foreign policy stance towards the Arab-Israeli conflict, we argue that the gap is dynamic and has changed across time. In the absence of an internationally and locally recognised border between Israel and Palestine, the Europeans have aimed at constructing one on the 1949 armistice line, the so-called Green Line. They have done so in stages, by first formulating a discursive practice about the need for a border, then establishing economic practices in the late 1980s-early 1990s, and most recently practicing a legal frame of reference for relations with Israel and the Palestinian Authority (PA) based on the Green Line. The outcome is that, for what concerns European countries and EU legislation, the Green Line has been increasingly taken as the Israeli-Palestinian border. However, gaps never fully close and more contemporary events seem in fact to point to a re-opening of the gap, as the article explores.     

The “inflow-effect”—Trader inflow and price efficiency

We investigate the impact of cash and trader inflow on price efficiency in multi-period experimental asset markets. Implementing eight treatments with 672 subjects, we find that (i) the joint inflow of cash and traders triggers strong overvaluation and massive price run-ups (inflow-effect). Remarkably, the effect occurs in almost all of the 30 markets with joint cash and trader inflow and is very robust. The effect even prevails in markets with complete and symmetric fundamental information. We further show that (ii) in treatments with the joint inflow of cash and traders, prices crash to fundamentals towards maturity of the asset. The analysis of traders׳ beliefs reveals that (iii) despite fundamental values staying constant, beliefs about fundamentals co-move with upwardly trending prices. Finally, we report a speculative motive only among the optimists in treatments where we observe the inflow-effect.     

Regime switching and the (in)stability of the price–rent relationship: evidence from the US

Present value models of house prices assert that in the absence of self-fulfilling bubbles, a house price is equal to the present discount value of all future rents, which implies a linear relationship between house price and rent, and hence a stable price-to-rent ratio. Using a Markov switching error correction model, we re-examine this relationship in the US housing market and find two distinctive regimes: one with a long-run relation between house price and rent predicted by the present value models and the other in which the relation is nonlinear. Furthermore, we find evidence that deviations of house prices from the present value models’ predictions are caused by the overreaction of house prices to movements in rents rather than speculative bubbles attributable to extraneous factors.     

Migrants’ well-being during the global financial crisis: Economic and social predictors

This paper investigates the economic and social predictors affecting the well-being of temporary migrants before, during and after the financial crisis. Exploiting unique panel data which cover migration spells from Tajikistan to Russia between 2001 and 2011, we find that migrants earn less but stay longer in the destination during the crisis; at the same time, they become more exposed to illegal work relations, harassment and deportation through the Russian authorities. The overall income loss can be attributed to wage cuts and to rising illegal employment that is generally poorly paid. Despite the similarities in the demographics and jobs of migrant workers, we find substantial heterogeneity in how the financial crisis affects their well-being. Migrants who experience wage losses during the crisis rationally stop migrating.     

Corporate social responsibility and the ‘game of catallaxy’: the perspective of constitutional economics

The paper examines the issue of corporate social responsibility (CSR) from the perspective of constitutional economics, focusing on the distinction between a political community’s constitutional choice of the rules of the “market game,” and the market players’ sub-constitutional choice of strategies within these rules. Three versions of CSR-demands are identified and discussed, a “soft,” a “hard”, and a “radical” version. The soft version is concerned with the issue of how “socially responsible” corporations ought to play the market game within existing rules. The hard version is about how the rules of the market ought to be changed in order to induce “socially responsible” corporate behavior. And the radical version questions the compatibility of CSR and the logic of the market game, calling in effect for adopting some alternative economic regime.

Market Inertia and the Introduction of Green Products: Can Strategic Effects Justify the Porter Hypothesis?

If, according to Porter’s hypothesis, a “greener” strategy is more profitable, why may its implementation need regulatory intervention? We present a repeated Cournot duopoly where the market may exhibit inertia towards the adoption of even cost-efficient environmental goods. With consumers recognizing that a product is green only with a time lag, if a firm unilaterally adopts the green product initially loses profit due to (a) increased costs (direct effect) and (b) reduced market share (strategic effect). By imposing simultaneous adoption, regulation eliminates (b), thus enhancing long-run profitability. Through a similar mechanism a government can increase its domestic firms’ international market share and profits by forcing them to simultaneously adopt the green product.     

Equity risk premium and time horizon: What do the U.S. secular data say?

We consider a representative investor whose wealth is made up of the equity market portfolio and the riskless asset, and who maximizes the expected utility of his/her future wealth for a given horizon. The solution of this program shows that the equilibrium value of the equity risk premium – the latter being measured by the difference between the expected equity portfolio return and the risk-free interest rate – is given by the product of the price of risk by the expected variance of stock returns. When returns are predictable, these two magnitudes are both time-varying and horizon-dependent. In accordance with this theoretical framework, our paper presents an econometric model of the equity risk premia for two traditional horizons: the one-period-ahead horizon (i.e. the ‘short-term’ premium) and the infinite-time horizon (i.e. the ‘long-term’ premium). Using annual US secular data from 1871 to 2008, and representing the expected returns by mixing the three traditional adaptive, extrapolative and regressive processes, large disparities in the dynamics of the two premia are evidenced. Concerning the determination of the equilibrium values of the two premia, the expected variances depend on the past values of the centered squared returns while the prices of risk (unobservable variables) are estimated according to the Kalman filter methodology, which enables us to capture the influence of hidden variables and of non-directly measurable psychological effects. A spread of interest rates adds to this determination. Possibly due to risky arbitrage and transaction costs, the results show that observed premia gradually converge towards their equilibrium values, this process being described by an error correction model. Overall, our model provides a rather satisfactory representation of ‘short-term’ and ‘long-term’ premia.     

A “penalty” discount rate,bank behavior,and price and output stability

The purpose of this paper is to provide an evaluation of the implications of the adoption of a penalty rate discount window policy for bank behavior and for price and output stability. A basic model of the banking firm is used to show that adoption of a penalty rate policy alters the sensitivity of bank portfolio demands to changes in the open market rate, to which the penalty discount rate is deterministically related. In the context of a macroeconomic model that takes into account this interaction of discount window policy and bank behavior, it is demonstrated that adoption of a penalty rate policy generally would have ambiguous implications for the variability of real output and the price level.     

Drought and social conflict in rural Zimbabwe: Does the burden fall on women and girls?

Climate change–induced extreme weather events such as drought have occurred with increasing frequency and intensity in Zimbabwe over the past 30 years bringing about pressure on communally owned water resources. Using the Zimbabwe Vulnerability Assessment Committee 2020 survey of rural households in Zimbabwe, this study assesses the impact of drought shock on the occurrence of water point violence. The impact of self-reported drought shock on the likelihood of occurrence of social conflict in the form of water point violence is subject to confounding due to selection bias. Using the doubly robust inverse probability weighted regression adjustment to account for confounding, we investigate gender dimensions of the impact of drought on inducing water point violence in rural Zimbabwe. The study offers three major findings. First, drought shock is associated with increased household propensity to experience water point violence. Second, the severity of the drought shock impact increases the probability of the household experiencing water point violence. Third, drought shock–induced water point violence is only statistically valid for households where the water-fetcher is a woman or girl. The results suggest that the impact of drought shocks on water point violence is gendered and disadvantages women and girls more than men and boys.     

Social and solidarity economy and social and solidarity commons: Towards the (re)discovery of an ethic of the common good?

This research poses the ethic of the common good and the institutions of the social and solidarity economy (SSE) as the foundation of commoning practices. Specifically, it illustrates how the latter may contribute to regenerating the commons, fostering open and shared access to key productive resources and essential goods and services. The analysis focuses on social and solidarity commons (SSC), defined as all those relational practices that contribute to the accumulation and regeneration of human and social (as well as other types of) critical capital. To achieve this research goal, this study collected new and old issues debated in the academic literature concerning the geographic nature of commons and their juridical and economic treatment within socioeconomic disciplines. Then, a historical overview of the commons highlights their dynamic and multifaceted nature and illustrates how they have often been co‐owned and co‐governed according to shared rules and norms. Within this general framework, SSC are introduced, and a role for the institutions of the SSE is proposed to foster an ethic of the common good as a necessary (but not sufficient) condition for expanding and enforcing people's participation in commoning practices.     

Income–happiness paradox in Australia: Testing the theories of adaptation and social comparison

This paper investigates whether the theories of adaptation and social comparison can explain the income–happiness puzzle (Easterlin Paradox) in Australia. Alternative specifications of happiness model that incorporate adaption, comparison incomes and other relevant variables are estimated using the panel data from the five waves (2001–2005) of the Household Income and Labour Dynamics in Australia (HILDA) surveys. The statistical tests provide no support for the adaptation effect on happiness. However, we find strong support for the theory of social comparison as an explanation for the happiness paradox. An increase in peer group income hurts the poor more than the rich, suggesting that a redistribution of income is likely to enhance the overall wellbeing of society. A sensitivity analysis is conducted to check the robustness of results.
