Replicating Walrasian equilibria using markets for membership in labor-managed firms

In standard models of the labor-managed firm, labor is misallocated in the short run. This problem can be eliminated by introducing a market for membership in each firm. These markets substitute for the capitalist labor market and support equilibria isomorphic to Walrasian equilibria. Such LMFs resemble familiar Ward-Domar-Vanek LMFs by ensuring that firm sizes are optimal for ex post members, but they also have the property that firm sizes are optimal for workers endowed with ex ante membership rights.     

Managerial style and the strategic choice of executive incentives

This paper analyzes a two-stage duopoly model where owners provide incentives to managers who then select output levels. Unlike the previous Cournot models on the strategic use of incentives (e.g. Fershtman and Judd, 1987; Sklivas, 1987), managers hold different beliefs about their rivals. Managers and executives are classified by ‘management style’ based on the aggressiveness of their beliefs. It is shown that many of the standard results of the strategic managerial incentive literature no longer hold when executives have differing managerial styles. For example, owners may ‘penalize’ their managers for sales, or they may optimally instruct their managers to maximize profits, in contrast to the standard Cournot findings. Indeed, the model yields a necessary and sufficient condition for compensation contracts to specify pure profit-maximizing behavior when managers have differing managerial styles. Thus, the analysis suggests that when ownership and control are separated, owners must carefully assess the belief structure (management style) of their executives before designing the compensation package.     

Exchange rate bifurcation in a stochastic evolutionary finance model

This paper analyzes the stability and fluctuations of the exchange rate with a speculative bubble using the methods of evolutionary finance and stochastic differential equations. It constructs a hybrid stochastic system for the financial market involving a discrete time process and a continuous time process. The discrete process models the bubble and is meant to capture the behavior of less sophisticated investors who trade infrequently. The continuous time process is a stochastic differential equation for monetary policy together with a backward stochastic equation for the exchange rate. Monetary policy is affected by the bubble and in turn affects the exchange rate as well as speculation. The bubble and exchange rate exhibit a form of bifurcation. This means the bubble and exchange rate experience fluctuations as the propensity to chase trends or switch predictors changes.     

Local martingales, arbitrage, and viability Free snacks and cheap thrills

Summary. We revisit a standard model of security prices as Ito processes, and provide some new economic insights about the role of arbitrage and credit limits within such a model. We show that the standard assumptions of a positive state prices and existence of an equivalent martingale measure exclude prices that are viable models of competitive equilibrium and that are potentially useful for modeling actual financial markets. These models have been dismissed in the past as allowing arbitrage, but in fact an agent who prefers more to less and who has limited access to credit may have an optimum.

An Insiders' View of FCC Spectrum Auctions

After a long period of awarding spectrum licenses inefficiently, changes in the budget and budgetary process coupled with increases in the value of the spectrum for non-broadcast use led Congress to allow the Federal Communications Commission to award licenses through competitive bidding. Contrary to the perceived view of government bureaucracies as excessively cautious, the FCC used the newfound authority to adopt a novel approach to auction design—simultaneous multiple round auctions. The innovative auction design would not have been adopted without the successful collaboration between government economists and academic economists, who helped to formulate and refine the design so that decision makers at the FCC could be convinced that the novel technique was both superior and practical. The FCCs implementation of competitive bidding was not only rapid as mandated by Congress, but also much less costly than outside alternatives and allowed the integration of spectrum policy decisions and auction design. Experience from several auctions has led to a number of open questions and refinements. The FCC is trying to replicate the success with the original auction design by facilitating dialog between the agency and outside auction experts in order to address these issues.     

The effect of social distancing on the reach of an epidemic in social networks

How does social distancing affect the reach of an epidemic in social networks? We present Monte Carlo simulation results of a susceptible–infected–removed with social distancing model. The key feature of the model is that individuals are limited in the number of acquaintances that they can interact with, thereby constraining disease transmission to an infectious subnetwork of the original social network. While increased social distancing typically reduces the spread of an infectious disease, the magnitude varies greatly depending on the topology of the network, indicating the need for policies that are network dependent. Our results also reveal the importance of coordinating policies at the ‘global’ level. In particular, the public health benefits from social distancing to a group (e.g. a country) may be completely undone if that group maintains connections with outside groups that are not following suit.

     

Comparison of Important Laws Governing the Macroeconomies of Taiwan and China

This is a comparative study of the important laws governing the macroeconomies of Taiwan and China. The laws are concerned with consumption, investment and fiscal and monetary policies of the government. Following similar studies on China, the present paper focuses on the case of Taiwan. Using annual data from 1961 to 2014 we find that the consumption function satisfies the permanent income hypothesis of Friedman and the investment function satisfies the accelerations principle as in the case of China. Money supply does not affect GDP but government expenditure has a positive effect on consumption and a negative effect on investment. These results are opposite to those obtained for China. Explanations of the differences are given.     

Price competition in the market for business telecommunications services

We estimate a two-step control-function model that relates incumbent prices for small-business telecommunications services to the number of facilities-based entrants, cost, demand, regulatory conditions, and a correction for endogenous market structure. Results show that the price effects from entry are understated in ordinary least squares regressions. When controlling for endogeneity, prices are negatively related to the number of entrants, indicating that markets without a competitive presence could exhibit market power. These findings should prove helpful to the Federal Communications Commission and other State regulators determining the conditions under which price and other forms of regulation may be relaxed.     

Integrating science and local knowledge in environmental risk management: A decision-focused approach

This paper explores how a structured decision process, based on methods from the decision sciences, can contribute to the integration of local and scientific knowledge in environmental decision making. Emphasis is placed on the use of key decision structuring steps and analytical tools to help ensure the systematic treatment of both fact-based and value-based knowledge claims. Practical methods are discussed for communicating and evaluating values and technical information across participants and cultures in ways that are methodologically rigorous and encourage different sources of credible knowledge to be considered on equal footing. Examples are presented from water use planning in British Columbia, Canada, where stakeholder consultations at 22 hydroelectric facilities demonstrate specific techniques that can be used to clarify values, to explore hypotheses, to clarify uncertainties, to identify and evaluate options, to make value-based choices, and to facilitate mutual learning.     

Asymmetric effects of housing wealth on college enrolment

We investigate the impact of housing wealth, credit availability and financial distress on college enrolment decisions. We find that housing wealth is negatively related to enrolment in public schools and positively related to enrolment in private schools. This evidence suggests that, on average, students substituted away from private schools towards public institutions during the recent financial crisis.
