Taxes and executive stock options

In the Sixties, the qualified stock option was the predominant form of long-term incentive compensation contract for major industrial firms in the U.S. In the early Seventies these same firms replaced their tax-qualified stock option plans with non-qualified sttock options and later modified these plans to include a variety of new contingent compensation arrangements, some of which were based on accounting numbers instead of stock prices. This paper develops the hypothesis that tax considerations play an important role in explaining the form of compensation contracts. The pattern and timing of changes in the compensation plans of the top 100 industrial firms provides evidence consistent with the tax hypothesis.     

Unanticipated money,output, and prices in the small economy

A macroeconomic model for an open economy experiencing both domestic and international monetary disturbances is given. Expectations are assumed to be rational. Particular attention is focused on the reduced form coefficients for unanticipated domestic and foreign monetary disturbances under alternative exchange rate regimes.     

Unemployment insurance: The role of electoral systems and regional labour markets

Levels of insurance against unemployment vary considerably across countries. Replacement rates, the ratio relating income from unemployment to what people earned when they were employed, are higher in countries with proportional electoral systems than in countries with majoritarian systems. Also, replacement rates are positively correlated with per capita income and negatively correlated with the countries' unemployment rates. I develop an electoral competition model that replicates these stylized facts.     

Mega‐Regional Agreements and Their Impact on Australia

This paper estimates the effects of emerging mega‐regional agreements on the economy of Australia using a Computable General Equilibrium model. Scenarios considered include the 11‐member Comprehensive and Progressive Agreement for Trans‐Pacific Partnership (CPTPP) agreement, its possible enlargement to include five additional members (‘TPP16’) and the Regional Comprehensive Economic Partnership (RCEP) currently under negotiation. The study finds that Australia stands to enjoy real income and trade gains along both the CPTPP and RCEP paths. However, since Australia is already benefiting from its own liberal trade policies and many prior trade agreements, benefits are relatively modest, typically below one per cent of real income.     

Complex solutions of nonconcave dynamic optimization models

Summary In this paper we consider a class of time discrete intertemporal optimization models in one dimension. We present a technique to construct intertemporal optimization models with nonconcave objective functions, such that the optimal policy function coincides with any pre-specifiedC ² function. Our result is a variant of the approach presented in a seminal paper by Boldrin and Montrucchio (1986). Whereas they solved the inverse problem for the reduced form models, we address the different question of how to construct both reduced and primitive form models. Using our technique one can guarantee required qualitative properties not only in reduced, but also in primitive form. The fact that our constructed model has a single valued and continuous optimal policy is very important as, in general, nonconcave problems yield set valued optimal policy correspondences which are typically hard to analyze. To illustrate our constructive approach we apply it to a simple nonconcave model.We are grateful for the helpful comments of L. Montrucchio, K. Nishimura, T. Mitra and an anonymous referee.

Median stable matching for markets with wages

We define the median stable matching for two-sided matching markets with wages and prove constructively that it exists.     

Nominal inertia and shock persistence in UK business cycles

A structural VAR methodology is used for UK data to identify and map out the effects of innovations in the money supply, employment, output, wages and prices. Moreover, bands of two standard errors are computed for the impulse response functions so that comment may be made on the significance of the dynamic responses of the variables to the simulated shocks. This allows conclusions to be drawn on the persistence of shocks. Results suggest that output variation is largely determined by aggregate demand shocks over the business cycle frequency. Importantly, evidence is also found of rigidities in the form of price inertia and nominal wage stickiness.     

Social Networks and Economic Sociology

A bstract The social network metaphor is widely used by sociologists to study socioeconomic behavior and processes The use of social networks generally takes place within the ranks of sociology However, a more complete social science would result by combining work being done on social networks within sociology with mainline economic theory The insights from such a research agenda will help us better understand socioeconomic behavior With this in mind, the main objective of this paper is to demonstrate the utility of the network metaphor to economists This objective will be accomplished through developing four basic components of social networks, and using them to navigate through the existing literature in economic sociology Furthermore, topics for future research in which social networks can provide contributions to the explanation of socioeconomic behavior are explored as well     

Labour contracts in a stock market economy

In this paper, labour contracts are examined in the context of a general stock market economy where all shareholders are risk averse, and firms act in shareholders interest. The problem considered is whether some firm can offer a wage contract that will make all its shareholders better off. We show by example that, contrary to the arguments in the partial equilibrium framework, it is possible that no such contract will exist, even when there are potential gains to risk sharing. A sufficient condition for the existence of a feasible pareto improving contract is given. It is shown that contract trading will arise provided some firm has no large shareholders.
