On the missing equation: A reply

Shaller's criticism of our paper improperly interprets our model. Furthermore, his proof either assumes that the aggregate supply and demand curves are identical, or ignores that factor market demand already incorporates aggregate demand.     

The missing equation: The wedge model alternative

This article develops an alternative method for solving the problem of the “missing equation” by including the market-nonmarket decision for factors and capital-labor mix decision for producers. The result is a wedge or supply-side model of the economy. This general equilibrium macro model describes the interaction between the product and factor markets, describes both the income and substitution effects of government actions, and provides new insights into the full impact of the government sector.     

On the Anthropological Study of Economies: A Comment

This paper deals with the moral justification behind policy positions. Squeezed between the inevitability of having a welfare ideology and the mantra of value-neutrality (depoliticization), neoclassical policy economists tend to disguise their normative positions on policy matters as common sense. This attitude is particularly pronounced in what I will call "the rhetoric of worthiness," whereby the neoclassical approach justifies its advocacy that certain people should not be helped. This normative position is disguised by a vocabulary (e.g., moral hazard) claimed to be politically neutral. The present paper criticizes this neoclassical mode of policy evaluation in favor of a more socially conscious and innovative policy approach.     

On the definition of externality as a missing market

Within the general equilibrium framework, externalities are regarded as missing markets which invalidate the first theorem of welfare economics. As witnessed by some authors’ positions in the 1970s, this definition does not highlight whether or not it is an exogenous and an unintended effect. These ambiguities raise the issue of the relation between the basic formalisation of an externality (a dependence of individual objective functions) and its economic meaning (a missing market). Finally, they also raise the more general issue of the dilution of externality in the larger notion of individual interaction.     

On policymakers’ loss functions and the evaluation of early warning systems: Comment

Sarlin (2013) suggests that if a loss function approach is chosen to derive the optimal threshold for financial crisis early warning indicators, the loss function specification should explicitly take into account the unconditional sample crisis probability. In this comment we argue that this approach is not robust to small perturbations of the preference parameter and is not easy to use for policy purposes. We suggest therefore to continue using a simpler loss function specification.     

On the consequences of trend for simultaneous equation estimation

It is shown that the presence of trend in the exogenous variables violates some standard assumptions that govern large sample asymptotics in simultaneous equations, and that contrary to the standard analysis Ordinary Least Squares may be consistent with trended data. Necessary and sufficient conditions are derived for this to happen, and in case of consistency the asymptotic distributions for a wide class of k-class estimators are shown to be identical.     

Russian experts: missing actors of the budget process

Abstract

This article provides an examination of the role of experts in the Russian budget process. Experts are those whose role is based on specialised knowledge and technical skills, rather than affiliation to an agency, association or political party. Ideally their contributions are impartial. In the first part of the article the channels of expert influence are described, primarily within the executive branch. Features are found in these channels that mean that impartial advice is not always guaranteed. In the second part, on the basis of a survey of experts, the answers to two questions are sought: whether they feel that impartial advice is expected of them and whether they provide it. There are negative elements in the responses on both counts, suggesting that despite some evidence of demand for such advice on the part of policy-makers, expert advice is often not impartial.     

The missing shock: the macroeconomic impact of British Privatizations

In this paper the impact of privatization on macroeconomic performance in the United Kingdom is tested using quarterly data from 1979 to 1999. Privatization proceeds have been included in a simple analytical framework dealing with both demand and supply-side of the economy. Multivariate cointegration techniques have been used in order to consider the nonstationarity of the time series involved. The empirical results show that privatizations have no long-run effects on output in the UK. This result is consistent with microeconomic evidence that shows that in the UK ownership change per se had little impact on long term productivity trends. Moreover it is found that privatization proceeds have contributed to sustaining public expenditures.     

Relative wage concern: the missing piece in the contract multiplier?

Recent research has cast serious doubts on the explanatory power of staggered wage/price setting to account for both output and inflation persistence following money shocks. This paper extends a dynamic general equilibrium model with wage staggering by incorporating relative wage concern on the part of workers. In sharp contrast to previous analyses, in this model both output and inflation dynamics exhibit substantial persistence. Moreover, persistence results hold for a wide range of parameterisations. Our results suggest that relative wage concern may be the missing piece in the money shock persistence puzzle.
