The allocation of ideological structures

This article tries to make allocation in the sociology of knowledge more teachable. What may appear as a sectarian magic is transformed into a rational procedure to be used by teacher and student alike. Allocation requires a number of steps by which (1) the ideological structure is made part of an ideology; and (2) the ideology is related to a particular social situation of past or present either by reflecting it in symbolic expression or by reflecting the exact opposite.The old puzzle of how ideological relativism can be asserted from a theoretical position, which — by social background — cannot be anything but relative in itself, falls by the wayside. Temporarily positivism is claimed for any viewpoint which allows empirical verification. It asserts its relativisim but never reaches absolute and final truth. Relative advantages only can be claimed for the many comprehensive social theories at any given time.The term imputation is replaced by the term allocation in this article. Imputation is a direct translation of the German word Zurechnumg. Borrowed from economic theory, this term is unnecessarily complicated. We cannot do more than allocated ideologies in a manner not amenable to precise numerical imputation.     

Economic Distance and Cross-Country Spillovers

Rates of long-run economic growth are not independent across countries. To account for this dependence we decompose the spatial covariance function of growth rates into a function of each countrys own observable characteristics, its unobservable characteristics, and cross-country spillovers. We use original data on economic distance to structure observed variation in countries long term growth rates. We use this structure to estimate the magnitude of economic interdependence among nations, and to give a nonparametric characterization of the relationship between economic distance and the magnitude of cross-country spillovers. These spillovers turn out to be quite important, accounting for more of the spatial covariance in growth rates than unobservable variables, and by some measures rivalling the importance of the countrys own observable characteristics.     

A trend filtering method closely related to $$\ell _{1}$$ trend filtering

The filtering method developed by Kim et al. (SIAM Rev 51:339–360, 2009), \(\ell _{1}\) trend filtering, is attractive because it enables us to estimate a continuous piecewise linear trend. This paper introduces a new filtering method closely related to \(\ell _{1}\) trend filtering in order to contribute to the accumulation of knowledge on \(\ell _{1}\) trend filtering. We show that the piecewise linearity, which is the key feature of \(\ell _{1}\) trend filtering, is derived from the new filtering. For this reason, we refer to the filtering as ‘pure’ \(\ell _{1}\) trend filtering. We also demonstrate some other miscellaneous results concerning the new filtering.     

Extreme bound analysis for residential load curve models

Using the theory ofLindley andSmith andSmith a hierarchical load curve model is applied to 16 households in a Southern Californian electricity demand study. Using the global sensitivity concept ofLearner [1982] we carry out an extreme bound analysis for the first stage load curve coefficients. The following three models are employed: Model 1, a quadratic load curve model without economic variables. Model 2, a quadratic load curve with four economic variables. Model 3, a cubic load curve with four economic variables. The posterior mean of these models are given by matrix weighted averages of the ordinary least squares (OLS) estimate of the first stage parameters and the GLS-estimates of the second stage parameters. The set of all estimates are given by a natural extreme bound analysis and the restricted bound analysis based on bounds for the second stage covariance matrix \(\hat \sum \) .     

A term structure model with preferences for the timing of resolution of uncertainty

Summary In this paper we present a model of the term structure of interest rates with imperfect information and stochastic differential utility, a form of non-additive recursive utility. A principal feature of recursive utility, that distinguishes it from time-separable expected utility, is its dependence on the timing of resolution of uncertainty. In our model, we parametrize the nonlinearity of recursive utility in a way that corresponds to preferences for the timing of resolution. This way we show explicitly the dependence of prices on the rate of information, as a consequence of the nature of utilities. State prices and the term structure of interest rates are obtained in closed form, and are shown to have a form in which derivative asset pricing is tractable. Comparative statics relating to the dependence of the term structure on the rate of information are also discussed.We thank Bob Hodrick and Matt Jackson for their comments.

This paper presents the first model of an earlier, preliminary working paper titled: Two models of price dependence on the timing of resolution of uncertainty.     

Moment Estimation of the Probit Model with an Endogenous Continuous Regressor

We propose a generalized method of moments (GMM) estimator with optimal instruments for a probit model that includes a continuous endogenous regressor. This GMM estimator incorporates the probit error and the heteroscedasticity of the error term in the first‐stage equation in order to construct the optimal instruments. The estimator estimates the structural equation and the first‐stage equation jointly and, based on this joint moment condition, is efficient within the class of GMM estimators. To estimate the heteroscedasticity of the error term of the first‐stage equation, we use the k‐nearest neighbour (k‐nn) non‐parametric estimation procedure. Our Monte Carlo simulation shows that in the presence of heteroscedasticity and endogeneity, our GMM estimator outperforms the two‐stage conditional maximum likelihood estimator. Our results suggest that in the presence of heteroscedasticity in the first‐stage equation, the proposed GMM estimator with optimal instruments is a useful option for researchers.     

The Determinants of Capital Structure Choice: Evidence from Polish Companies

The main objective of this paper is to investigate which of the two competing capital structure theories – the pecking order of financing choices or the traditional static trade-off model – better describes the financing decisions in Polish companies traded on the Warsaw Stock Exchange (WSE). The data come from financial statements of the companies and cover a 5-year period, 2000–2004. First, a correlation is run in order to separate a set of significant factors influencing the capital structure from the list of the following independent variables: assets structure, profitability, growth opportunities, liquidity, firm size, product uniqueness, earnings volatility, non-debt tax shields, dividend policy, and the effective tax rate. Next, in order to test the relationship between capital structure and its potential determinants, multiple regression is run. The evidence generally suggests the relevance of the pecking order hypothesis in explaining the financing choices of Polish firms.

The contributions of technical and allocative efficiency to the economic performance of European railways

This paper provides an empirical analysis of the relative contributions of allocative and technical efficiency to the productivity performance of European railways over the period 1972 to 1999. A stochastic frontier approach is used to analyse the cost structure of the railway industry. We estimate a translog cost system in which allocative inefficiency is modelled through an exact relationship between the cost share equations and the cost function. To allow the estimation of such a model using the sample theory approach we assume that the share equation residuals represent deviations from first-order conditions and, therefore, that they represent exclusively allocative inefficiencies. The use of this simplifying assumption renders our analysis computationally tractable, but it could be inconsistent with the economic theory of duality and for that reason caution is required in interpretation of results. Acknowledging this caveat, we find that European railways have experienced significant cost increases due to inefficient behaviour, with a mean value of around 15%. In contrast to previous studies, however, our estimates indicate a larger role for allocative inefficiency, which accounts for around of a half of the total increase in cost inefficiency.

A multidimensional spatial lag panel data model with spatial moving average nested random effects errors

This paper focuses on a three-dimensional model that combines two different types of spatial interaction effects, i.e. endogenous interaction effects via a spatial lag on the dependent variable and interaction effects among the disturbances via a spatial moving average (SMA) nested random effects errors. A three-stage procedure is proposed to estimate the parameters. In a first stage, the spatial lag panel data model is estimated using an instrumental variable (IV) estimator. In a second stage, a generalized moments (GM) approach is developed to estimate the SMA parameter and the variance components of the disturbance process using IV residuals from the first stage. In a third stage, to purge the equation of the specific structure of the disturbances a Cochrane–Orcutt-type transformation is applied combined with the IV principle. This leads to the GM spatial IV estimator and the regression parameter estimates. Monte Carlo simulations show that our estimators are not very different in terms of root mean square error from those produced by maximum likelihood. The approach is applied to European Union regional employment data for regions nested within countries.     

Consistency of Heckman-type two-step estimators for the multivariate sample-selection model

This analysis shows that multivariate generalizations to the classical Heckman (1976 Heckman, JJ. 1976. The common structure of statistical models of truncation, sample selection and limited dependent variables and a simple estimator for such models. Annals of Economics and Social Measurement, 5: 475–92.  [Google Scholar], 1979) two-step estimator that account for cross-equation correlation and use the inverse Mills ratio as correction term are consistent only if certain restrictions apply to the true error-covariance structure. An alternative class of generalizations to the classical Heckman two-step approach is derived that condition on the entire selection pattern rather than selection in particular equations and, therefore, use modified correction terms. It is shown that this class of estimators is consistent. In addition, Monte-Carlo results illustrate that these estimators display a smaller mean square prediction error.     

Taxation and the sustainability of collusion: ad valorem versus specific taxes

Assuming constant marginal cost, it is shown that a switch from specific to ad valorem taxation that results in the same collusive price has no effect on the critical discount factor required to sustain collusion. This result is shown to hold for Cournot oligopoly when collusion is sustained with Nash-reversion strategies or optimal-punishment strategies. In a Cournot duopoly model with linear demand and quadratic costs, it is shown that the critical discount factor is lower with an ad valorem tax than with a specific tax that results in the same collusive price. However, in contrast to Colombo and Labrecciosa (J Public Econ 97:196–205, 2013) it is shown that the revenue is always higher with an ad valorem tax than with a specific tax.     

Institutions Rule: The Primacy of Institutions Over Geography and Integration in Economic Development

We estimate the respective contributions of institutions, geography, and trade in determining income levels around the world, using recently developed instrumental variables for institutions and trade. Our results indicate that the quality of institutions trumps everything else. Once institutions are controlled for, conventional measures of geography have at best weak direct effects on incomes, although they have a strong indirect effect by influencing the quality of institutions. Similarly, once institutions are controlled for, trade is almost always insignificant, and often enters the income equation with the wrong (i.e., negative) sign. We relate our results to recent literature, and where differences exist, trace their origins to choices on samples, specification, and instrumentation.     

The “Dorfman-Steiner” rule: The intertemporal case

Conclusion Ireland was right in pointing out the weaknesses of the equation of motion (1.1) in the original paper. However if one turns to a more specific formulation of this equation such as (1.3), it can be shown that the equality between and still holds true for the continuous case as for the discontinuous one.This reply has greatly benefited from comments by M. Beuthe and A. Bultez. The author remains solely responsible for any error.     

Term limits and pork barrel politics

We develop a dynamic model of democratic politics in which both potential office holders and the electorate have heterogeneous ideologies. Voters have incomplete information about candidate ideologies, so they must use information from previous positions taken in office to make informed re-election decisions. We characterize the effects of term limits on the evolution over time of the ideological positions taken by office holders and derive the implications for voter choice and welfare. Contributions of our paper include:

•

We detail how pork provision by more senior incumbents interacts with term limits to affect electoral outcomes. Pork provision—transfers of resources from districts with junior legislators to districts with more senior legislators—induces voters to be more forgiving of extreme location by incumbents, especially incumbents in small or poor districts. Pork provision can explain why re-election probabilities in Congress exceed those for governors.

-

Term limits reduce voter welfare when all that matters are the ideological positions taken by the office holder.

-

Term limits may be advantageous when senior incumbents can extract benefits for their constituencies at the expense of districts with more junior representatives. Large or rich districts especially value term limits when there is substantial pork provision.

•

We characterize the welfare of all voters, not just the median voter.

     

Export activity,persistence and mark-ups

This article addresses the differences in margins across exporting and nonexporting firms. We jointly estimate a translog cost function, a variable factor share equation and price-cost margin equations to analyse the effect of persistence in export activity on margins. Results indicate that nonexporters have smaller margins than persistent exporters and firms that entered foreign markets during the nineties. However, larger export ratio is negatively associated with margins for persistent exporters. It suggests that efficiency advantages for exporters are partially compensated by higher competitive pressure in international markets. These results are in accordance with the predictions of Melitz and Ottaviano (2005 Melitz, MJ and Ottaviano, GIP. 2005. Market size trade, and productivity, NBER Working Paper Series No. 11393 (forthcoming in The Review of Economic Studies) [Google Scholar]).     

Samuelson and Davidson on ergodicity: A reformulation

The concept of ergodicity in economics seems to have the qualities of a shibboleth—a word or saying used by adherents of a party, sect, or belief, and usually regarded by others as empty of real meaning. It is in use by both neoclassical economics—after Samuelson (1965 Samuelson, P. A. “Proof That Properly Anticipated Prices Fluctuate Randomly.” Industrial Management Review, 1965, 6 (2), 41–49.[Web of Science ®] , [Google Scholar], p. 43), who used the term in his paper on what later became a foundation of the efficient market hypothesis—and post Keynesian economics—after Davidson, who picked up the term in order to highlight methodological differences. Considering the origin of the concept in statistical physics and its use in the topology of dynamical systems, which most economists are not conversant with, the importance ascribed to ergodicity in economic debate seems mystifying. We deconstruct the meaning of the term in the major contributions of Samuelson and Davidson. We suggest an alternative to (non)ergodicity to discuss the nature of randomness in the real world. While neoclassical theory assumes stochastic randomness, post Keynesians assume nonstochastic randomness, a term developed by the mathematician Kolmogorov (1986 Kolmogorov, A.N. “On the Logical Foundations of Probability Theory.” In K. Ito, and J.V. Prokhorov (eds.), Probability and Mathematical Statistics, Moscow, 1986, pp. 467–471. [Google Scholar], p. 467). We argue that even in an ergodic world there is a problem with the idea that stochastic randomness can be dealt with by the financial system.     

Biological Adaptation in Human Societies: a ‘Basic Needs’ Approach

The groundzero premise (so to speak) of the biological sciences is that survival and reproduction is the basic, continuing, inescapable problem for all living organisms; life is at bottom a survival enterprise. It follows that survival is the paradigmatic problem for human societies as well; it is a prerequisite for any other, more exalted objectives. Although the term adaptation is also familiar to social scientists, until recently it has been used only selectively, and often very imprecisely. Here a more rigorous and systematic approach to the concept of adaptation is proposed in terms of basic needs. The concept of basic human needs has a venerable history – tracing back at least to Plato and Aristotle. Yet the development of a formal theory of basic needs has lagged far behind. The reason is that the concept of objective, measurable needs is inconsistent with the theoretical assumptions that have dominated economic and social theory for most of this century, namely, valuerelativism and cultural determinism. Nevertheless, there have been a number of efforts over the past 30 years to develop more universalistic criteria for basic needs, both for use in monitoring social wellbeing (social indicators) and for public policy formulation. Here I will advance a strictly biological approach to perationalizing the concept of basic needs. It is argued that much of our economic and social life (and the motivations behind our revealed preferences and subjective utility assessments), not to mention the actions of modern governments, are either directly or indirectly related to the meeting of our basic survival needs. Furthermore, these needs can be specified to a first approximation and supported empirically to varying degrees, with the obvious caveat that there are major individual and contextual variations in their application. Equally important, complex human societies generate an array of instrumental needs which, as the term implies, serve as intermediaries between our primary needs and the specific economic, cultural and political contexts within which these needs must be satisfied. An explicit framework of Survival Indicators, including a profile of Personal Fitness and an aggregate index of Population Fitness, is briefly elucidated. Finally, it is suggested that a basic needs paradigm could provide an analytical tool (a biologic) for examining more closely the relationship between our social, economic and political behaviors and institutions and their survival consequences, as well as providing a predictive tool of some value.     

Robust ergodic chaos in discounted dynamic optimization models

Summary We identify a family of discounted dynamic optimization problems in which the immediate return function depends on current consumption, capital input and a taste parameter. The usual monotonicity and concavity assumptions on the return functions and the aggregative production function are verified. It is shown that the optimal transition functions are represented by the quadratic family, well-studied in the literature on chaotic dynamical systems. Hence, Jakobson's theorem can be used to throw light on the issues of robustness of ergodic chaos and sensitive dependence on initial conditions.     

The Origins of the State from Reciprocity to Coercive Power

This paper attemptsto explain the process of emergence of the state. It argues thatmorality is the first institution created by human beings tomaintain social order. But social order based on morality breaksdown when the human group becomes too large. When that occurs,most groups tend to split. Some groups, however, are able todevelop a hierarchical structure that allows them to escape thatfate. Political leadership is described as the result of a socialcontract. It is argued that this contract undergoes an essentialchange along the process of consolidation of statehood. At someinitial stage, it can be regarded as a consent contract,but, later on, it becomes a duress contract. This processis related to three main causes: population growth, increasingeconomic interdependence and geographic confinement. Other topicsdiscussed in the paper are the origins of private property rights,the emergence of autocratic governments, and the origins of democracy.
