The production economics of economics production

How is new economic knowledge produced over time? That depends on how the expertise of authors is managed within economic journals. Using data from 41 major economics journals spanning 21 years (1994–2014), we find that both the intensive margin (article length) and extensive margin (article number) of the discipline have been growing. In particular, the extensive margin has outgrown the intensive margin, such that each article produces absolutely more but relatively less knowledge. This pattern is highly consistent with a model of within‐journal specialization. As predicted by the model, the share of an individual article shrinks less in general interest journals and in more prestigious journals, where expertise is less substitutable across topics.     

Global analysis and economics III: Pareto Optima and price equilibria

Among other things a global version of the fundamental theorem of welfare economics is proved. One starts with a pure exchange economy with fixed total resources where hypotheses of differentiability, convexity, and monotonicity are made on the utility functions. Let ? be the set of price equilibria where the initial allocation coincides with the final one. Then the map which assigns to such a price equilibrium, the corresponding allocation is a diffeomorphism (a complete correspondence) between ? and the set of Pareto Optima.     

Robust drivers of Bitcoin price movements: An extreme bounds analysis

There is a growing stream of empirical research that endeavors to identify the influential variables contributing to the price formation of cryptocurrencies and, in particular, Bitcoin. However, results of those studies generally remain inconsistent in terms of not only the true combination of factors that affect Bitcoin prices, but also the nature of effects (positive vs. negative) that each individual factor has on the price behavior. The present study investigates the robustness of a wide variety of candidate determinants that have been the focus of attention in relevant literature. Our inquiry relies on the extreme bounds analysis (EBA), which is a type of large-scale sensitivity analysis capable of addressing model uncertainty issues. The findings suggest that crypto market forces of supply and demand, public interest, and economic policy uncertainty are the only variables robust to all possible variations in the conditioning information set. Our evidence argues in favor of the predominance of cryptocurrency-related determinants over global macroeconomic and financial ones in explaining Bitcoin price movements.     

Oil price uncertainty and movements in the US government bond risk premia

In this paper, we analyze the predictability of the movements of bond premia of US Treasury due to oil price uncertainty over the monthly period 1953:06 to 2016:12. For our purpose, we use a higher order nonparametric causality-in-quantiles framework, which in turn, allows us to test for predictability over the entire conditional distribution of not only bond returns, but also its volatility, by controlling for misspecification due to uncaptured nonlinearity and structural breaks, which we show to exist in our data. We find that oil uncertainty not only predicts (increases) US bond returns, but also its volatility, with the effect on the latter being stronger. In addition, oil uncertainty tends to have a stronger impact on the shortest and longest maturities (2- and 5-year), and relatively weaker impact on bonds with medium-term (3- and 4-year) maturities. Our results are robust to alternative measures of oil market uncertainty and bond market volatility.     

The economics of retail firms

This paper identifies retail firms as an economic institution which delivers explicit products or services to consumer together with a variety of distribution services that determine the levels of distribution costs experienced by consumers in their purchase activities. The demand for the retailer's product is derived from a household production model in which the levels of distribution services provided by the retailer play the role of fixed inputs in the household's production functions. The supply of the retailer's product is derived from a joint cost function which is non-decreasing in the levels of distribution services provided. Profit-maximizing behavior in monopolistically competive markets shows that retail firms have special economic incentives to become complex organizations by integrating backwards, offering multiple explicit products and operating in more than one market. In addition, monopolistically competitive retail firms in long-run equilibrium will exhibit excess capacity, price dispersion and product choice in distribution services.     

Large price movements and short-lived changes in spreads,volume, and selling pressure

In this paper we examine changes in dollar and relative bid-ask spreads of stocks following large price movements. We investigate large increases and decreases separately and link our results to current market microstructure theories on trading activities and spreads. We also look at changes in volume and selling pressure to interpret the changes in trading activity. Our results show that the market reacts differently to price increases and decreases. For large price decreases, trading increases on the sell side even when spreads have increased. For large price increases, trading increases on the buy side during a period of higher spreads. However, the increases in dollar spreads and price pressure are most pronounced at the end of trading day. Our results are consistent with microstructure models that link trading activities and costs to the level of asymmetric information.     

The welfare economics of city bigness

Money wages will vary among cities in an economy with perfect labor mobility, due to differences in costs of producing nontraded goods. Commuting costs contribute to making money wages higher in large cities. Increasing negative technological externalities, such as pollution and congestion, also make money wages higher in larger cities. Such externalities tend to make big cities too big, because marginal is greater than average externality. Internalizing the externalities would be likely to make a city larger if the externalities emanate from production of nontraded goods, but might make the city smaller if the externalities emanate from export production.     

The public economics of self control

This paper analyzes self-control problems in intertemporal consumption of a sin good where current consumption imposes a negative externality on one’s future selves due to the existence of present-biased preferences. We introduce the negative externality dubbed ‘internality’, which is augmented by the cumulative distribution function of the sum of previous consumption. We show that the shot-run self with self-control problem over consumes the sin good compared to that of the long-run self without present-biased preferences. Further, we investigate the effectiveness of self-bargaining with the presence of an external control devise as possible punishment. The short-run self faces three possible options: do nothing, accept the long-run self’s offer, or reject the offer. In the latter case an external control devices is implemented. It is shown that successful self-bargaining depends on the efficiency of the control device.

The economics of nonprofit organisations' governance

We determine theoretically when we can expect agency problems amenable to shirking agents to arise in nonprofit organisations and derive the conditions for governance measures to remedy these. Agents' private benefits of shirking need to be considered combined with the effect of their efforts on the probabilities of being successful in fundraising and production. If this effect is large, agency problems can more easily be avoided. Sufficient conditions for governance measures to reduce agency problems are derived. The empirical literature fits a number of the results derived and shows important gaps, especially w.r.t. the role of success probabilities.     

The economics of markets and platforms

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.     

The politics and economics of decentralization

This paper analyzes a simple general equilibrium model with local public goods subject to exclusion and crowding. In general, no competitive equilibrium exists for such models. However, in this paper we study a four-person example, satisfying assumptions formulated in a paper by McGuire [Group segregation and optimal jurisdictions, J. Political Econ.82, 112–132 (1974)], in which a competitive equilibrium does exist. This example demonstrates that the model is capable of generating realistic implications regarding stratification of jurisdictions, the decision to subdivide or consolidate jurisdictions, reliance on exclusionary zoning, and the use of revenue sharing.     

The economics of public school closings

A community containing a fixed number of schools is assumed to close a school. A model is developed which traces the impact of the closing upon transportation costs, tax liability, quantity of education, and utility of the individuals residing in the city. The analysis suggests three explanatory variables that will affect a school closing decision by an optimizing school administrator. A test of the significance of these variables in predicting school closure decisions is conducted for the school district in Madison, Wisconsin.     

The urban economics of Adam Smith

The purpose of this paper is to show that location, transport costs, urbanization, and the urban hierarchy all play important roles in the economic analysis of Adam Smith.     

The economics of the Books of Moses

The Books of Moses contained economic precepts that made a twofold impact in the history of economic thought. First, Mosaic precepts shaped Israel's transition from a nomadic to a sedentary economy. This transition as such had parallels in many other societies, but Israel's case was unique in that Moses grounded economic precepts on theology. Second, Moses shaped conceptions of economics by Jews and by non‐Jews, in two ways: first, he laid a path for theologically derived economics that continued in Christianity and in Islam; second, he cast terms of reference for the right to own property that were dominant in Western economic thinking until the Enlightenment.
