Public policies as specification errors

Treating public policies as computable dynamic general equilibrium model specification errors offers computational and conceptional advantages for comparing models with data. The set of policies calculated to rationalize observed behaviors raises the substantive economic question whether, in any particular market, actual public policies sufficiently coincide with the model's behavior-rationalizing policies, or whether the model offers correct hypotheses about the determinants of demand and supply. As illustrations, public policies are calculated to rationalize, with respect to the stochastic neoclassical growth model, capital market behavior since WWII and labor market behavior in 1929–1950. One conclusion is that capital taxation drives a wedge between consumption growth and the expected pre-tax capital return, in the direction and amount predicted by the theory, and that capital taxation is the major intertemporal distortion in the postwar capital market. Second, a good theory of the Great Depression labor market must explain why measured MRS and MPL diverged so dramatically in 1929–1933 and why the wedge persisted.     

Accounting for the business cycle: Nominal rigidities, factor heterogeneity, and Austrian capital theory

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast, the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing. Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings. JEL classification B53, E12, E23, E32     

A sectoral analysis of the financial instability hypothesis

Hyman Minsky's Financial Instability Hypothesis (FIH) is applied to various North American Industrial Classification System (NAICS) industry groups, and it is found that some sectors develop much more closely in accordance with the FIH than others. Minsky categorized firms based on the relationship between cash flow and debt service requirements: hedge finance units, whose operating revenues are adequate to service current interest and principal on their debt; speculative finance units, which can meet interest payments but cannot pay down principal; and Ponzi finance units, which cannot meet current interest payments. The FIH is related to, as well as supportive of, Austrian Business Cycle (ABC) theory, because interest rates are negatively correlated with the proportion and market value of speculative firms in several sectors.     

The enduring allure of objective probability

Probability measures are properly considered subjective, if only as a result of the knowledge limitations of human experience. Even if objective probability can be demonstrated as an unambiguously verifiable property of the physical world, our necessarily imperfect access to such aspects of reality would necessitate the construction of subjective probability measures for examinations of human behavior. This paper will explore the distinction between subjective and purportedly objective probability in principle, and demonstrate that actual probabilities can only be subjective, at least ex ante. The paper will next examine the persistent efforts of philosophers, mathematicians, and particularly quantitatively-inclined social scientists, to construct and employ mistaken conceptions of purportedly objective probability. The neo-indeterminist interpretation of sub-atomic particle physics is addressed next, with its attempt to construct an objective-probabilistic account of reality based on the Heisenberg uncertainty principle. An explanation is suggested for the persistent allure of objective probability in the social sciences, which purports to offer a more economical and parsimonious basis for human behavior and the formation of expectations. The view that there are ontologically privileged, objectively-verifiable probabilities and expectations, will be examined and criticized. It appears to be one source of the discredited, though nonetheless widespread and persistent, belief in the efficacy and feasibility of central economic planning.     

Discrimination by Gender and Disability Status: Do Worker Perceptions Match Statistical Measures?

We explore whether perceptions of discrimination are related to ordinary statistical measures. The majority of disabled respondents report feeling some discrimination due to their disability, the majority of women feel some discrimination because of their gender, and a surprising number of men also report some discrimination. We do not find a strong link between perceptions of discrimination and measured discrimination perhaps because those who perceive discrimination feel that it occurs along other dimensions than pay. However, we do find a connection between whether a person feels his or her income is inadequate and measured discrimination for all groups studied.     

A stochastic production function for machine repair

Although work by Levhari and Sheshinski (1970) and Syrquin (1972) suggests that general functional forms, such as the Cobb–Douglas and CES, accurately approximate a machine-repair stochastic production process, this paper shows that these authors have not adequately captured the stochastic nature of the production process. More importantly, while general forms are convenient and widely employed, this paper argues that there is a more direct method for determining the properties of the production process.     

MULTIPLER EFFECTS AND STRUCTURAL CHANGE: APPLYING ECONOMIC BASE ANALYSIS TO SMALL ECONOMIES

Multiplier models (economic base, input-output, Keynesian) implicitly assume that pre-impact and post-impact interindustry transaction patterns are, for all practical purposes, identical. However, in very small regional economies this assumption is invariably violated because the economy undergoes a structural transformation during the impact process. That is, the economy often clearly shifts away from one functional type (e.g., service-oriented) toward another functional type (e.g., manufacturing-oriented) during the economic impact. Using marginal economic base analysis this paper outlines a model for predicting small-area impacts that captures not only the traditional multiplier effect but other effects related to (i) employment-based structural shifts and (ii) nonemployment-based contextual shifts. Algebraic and numerical derivations are given for the expected employment shifts in a hypothetical impacted economy. All numerical results follow from an earlier statistical analysis of the Arizona Community Data Set (ACDS).     

Shortage and currency substitution in transition economies: Bulgaria, Hungary, Poland, and Romania

This paper examines currency substitution in Bulgaria, Hungary, Poland, and Romania during the end of central planning and transition to market economies. Before liberalization, central European economies faced increasing shortage and repressed inflation in the official sector. Households held substantial wealth in real assets and foreign currency. Furthermore, part of their savings was held as hunting money against potential opportunities to buy in bulk at bargain prices in official stores or pay a premium price on the black market. The shift from centrally-planned to market economies is modeled with a shortage variable. Foreign currency demand and consumption functions are estimated by the Johansen procedure. Environmental constraints play a key role in interpreting estimates. The official sector shortage is an important determinant of foreign currency demand in each country.
