Incentives, Solidarity, and the Division of Labor

In this paper, we consider a version of the Holmstr¨om-Milgrom linear model with two tasks, production and administration, where performance is harder to measure in the latter. Both the principal and agent can devote effort to these tasks. We assume there are gains from specialization and that players have a preference for solidarity in work. As the gains from specialization increase, the principal eventually prefers to hire the agent solely for production purposes over autarky. As these gains increase still further, the principal increasingly specializes in administration and in the limit there is a complete division of labor. At the same time, the nature of the employment contract is transformed from one based on solidarity to one based on incentives. We therefore formalize aspects of the thought of Smith and Marx, who held that a division of labor leads to exchange and a deterioration in social relations.alienation, cooperation, division of labor, incentives, Marxism, reciprocity, solidarity

The Division of Labor and The Theory of the Firm

We extend the classical teams framework to the case where team size is endogenous and workers can specialize within a division of labor. We consider two institutions: equal-division partnerships and the firm with a budget-breaker. In contrast with the previous literature, we show that effort and team size in partnerships can be greater or less than first best. Our results for the firm are driven by two main insights. First, the budgetbreaker can increase effort with an increase in incentives and/or specialization. Second, incentives and employment are strategic substitutes. We show that the budget-breaker offers incentives that are weaker than first best or equal-division partnership incentives, so that shirking is more prevalent in the firm. Since incentives and team size are substitutes, the budget-breaker increases employment above the first best and partnership levels, so the firm is inefficiently large. The role of the budget-breaker is therefore to reduce agents' exposure to risk and to promote and coordinate specialization and the division of labor. The comparative statics of the firm are consistent with several institutional stylized facts (e.g., the size-wage effect) and recent organizational trends.budget-breaker, division of labor, endogenous team size, incentives, moral hazard, partnerships, size-wage effect, specialization, teams, theory of the firm

Nonstandard Foundations of Equilibrium Search Models

We develop an equilibrium sequential search model which includes most of the literature as special cases. In particular, the model can accommodate heterogeneity in buyers’ search costs and demand functions and firms’ cost functions, with general demand and cost functions. We identify conditions which ensure existence of equilibrium in pure strategies, utilizing recent progress in the theory of large games by Khan and Sun. These conditions elucidate the essential structure of equilibrium search models. Although we focus on sequential search, our methodology can be used for other classes of equilibrium search models as well.Search, equilibrium search models, nonstandard analysis

Anxiety and Performance: An Endogenous Learning-by-doing Model

In this article, we show that a standard economic model, the endogenous learning-by-doing model, captures several major themes from the anxiety literature in psychology. In our model, anxiety is a fully endogenous construct that can be separated naturally into its cognitive and physiological components. As such, our results are directly comparable with hypotheses and evidence from psychology. We show that anxiety can serve a motivating function, which suggests potential applications in the principal-agent literature.Diamond Paradox, price dispersion, search, strategic complementarities

Agency and Anxiety

In this paper, we introduce the psychological concept of anxiety into agency theory. An important benchmark in the anxiety literature is the inverted-U hypothesis which states that an increase in anxiety improves performance when anxiety is low but reduces it when anxiety is high. We consider a version of the Holmstrom-Milgrom linear principal-agent model where the agent conforms to the inverted-U hypothesis and investigate the nature of the optimal linear contract. We find that although high-powered incentives can be demotivational, a profit-maximizing principal never offers them. In contrast, the principal may optimally engage in a demotivational level of monitoring. Moreover, since risk can be motivational, the principal may refrain from eliminating it even when monitoring is costless. Indeed, the principal may even add pure noise to the contract in order to motivate the agent, contradicting the informativeness principle. Finally, incentives and monitoring can be strategic substitutes or complements in our model.

Inflation, Price Dispersion, and Market Structure

In this paper, we use a unique micro-level data set from Istanbul to investigate the empirical relationship between inflation and price dispersion. In particular, our data set includes price observations from three distinct store types: bakkals (convenience stores), pazars (bazaars), and supermarkets. Our findings indicate that pazars exhibit the least amount of price dispersion on average, which is consistent with the fact that menu and search costs are very low in the pazar and that such sellers seem to have very little market power. Moreover, we find that several of the basic inflation-dispersion channels identified by the theoretical literature seem to be operating in our data.inflation, market structure, menu cost models, micro panel data, price dispersion

Market Structure, Inflation, and Price Dispersion

In this paper, we investigate the impact of market structure on the relationship between inflation and price dispersion. We first propose a new empirical model of the relationship between inflation and dispersion with firmer theoretical foundations, and then extend the basic model to incorporate the potential effects of market structure. We estimate the basic and market structure specifications using a unique micro-level data set from Istanbul, which consists of monthly price observations from three different store types: convenience stores, open-air markets, and supermarkets. Our empirical findings support almost all of the basic and market structure predictions.inflation, market structure, menu cost models, micro panel data, price dispersion

Gender Differences in Russian Colour Naming

In the present study we explored Russian colour naming in a web-based psycholinguistic experiment (http://www.colournaming.com). Colour singletons representing the Munsell Color Solid (N=600 in total) were presented on a computer monitor and named using an unconstrained colour-naming method. Respondents were Russian speakers (N=713). For gender-split equal-size samples (NF=333, NM=333) we estimated and compared (i) location of centroids of 12 Russian basic colour terms (BCTs); (ii) the number of words in colour descriptors; (iii) occurrences of BCTs most frequent non-BCTs. We found a close correspondence between females’ and males’ BCT centroids. Among individual BCTs, the highest inter-gender agreement was for seryj ‘grey’ and goluboj ‘light blue’, while the lowest was for sinij ‘dark blue’ and krasnyj ‘red’. Females revealed a significantly richer repertory of distinct colour descriptors, with great variety of monolexemic non-BCTs and “fancy” colour names; in comparison, males offered relatively more BCTs or their compounds. Along with these measures, we gauged denotata of most frequent CTs, reflected by linguistic segmentation of colour space, by employing a synthetic observer trained by gender-specific responses. This psycholinguistic representation revealed females’ more refined linguistic segmentation, compared to males, with higher linguistic density predominantly along the redgreen axis of colour space

Building a feral future: Open questions in crop ferality.

The phenomenon of feral crops, that is, free-living populations that have established outside cultivation, is understudied. Some researchers focus on the negative consequences of domestication, whereas others assert that feral populations may serve as useful pools of genetic diversity for future crop improvement. Although research on feral crops and the process of feralization has advanced rapidly in the last two decades, generalizable insights have been limited by a lack of comparative research across crop species and other factors. To improve international coordination of research on this topic, we summarize the current state of feralization research and chart a course for future study by consolidating outstanding questions in the field. These questions, which emerged from the colloquium “Darwins' reversals: What we now know about Feralization and Crop Wild Relatives” at the BOTANY 2021 conference, fall into seven categories that span both basic and applied research: (1) definitions and drivers of ferality, (2) genetic architecture and pathway, (3) evolutionary history and biogeography, (4) agronomy and breeding, (5) fundamental and applied ecology, (6) collecting and conservation, and (7) taxonomy and best practices. These questions serve as a basis for ferality researchers to coordinate research in these areas, potentially resulting in major contributions to food security in the face of climate change
