Wage premia and skill upgrading in Italy: why didn't the hound bark?

This paper presents firm-level evidence on the change of the employment share and the wage premium of non-manual workers in Italian manufacturing during the nineties. We find that the relative stability of the aggregate wage premium and employment share hides offsetting disaggregate forces: technical progress raises the relative demand for skilled labor within firms, whereas demand changes associated with trade reduce the relative demand for skills. Moreover, it is within the class of non-manual workers that most of the action takes place: the wage premium and employment share of executives rise substantially, while those of clerks fall in a similar proportion. Finally, we find that the export status of firms plays a key role in explaining labor market dynamics: exporters account for most of both demand-related and technology-related shifts. Overall, our results for Italy question the conventional view that the labor market is “rigid” due to labor market institutions.     

Asset price targeting in an open economy with cognitive limitations: The best for macroeconomic and financial stability?

The choices of policy targets and the formation of agent expectations have been critical issues addressed by monetary policy management since the financial crisis of 2008. This paper evaluates macroeconomic stability in a new Keynesian open economy in which agents experience both cognitive limitations and asset market volatility. The (im)perfect credibility of various monetary policies (e.g., a Taylor-type rule with- or without asset price targeting, strict domestic inflation targeting, strict CPI inflation targeting, and exchange rate peg) may lead agents to react according to their expectation rules, and thus create various degrees of booms and busts in output and inflation. Simulations confirm that a Taylor-type CPI inflation targeting including an asset price target is the best choice. In contrast, the business cycles induced by Keynesian “animal spirits” are enhanced by strict inflation targeting. Furthermore, a credible exchange rate pegging system with an international reserve pooling arrangement can improve social welfare and stability in an open economy, even though its absolute value of the loss function is slightly lower than a Taylor-type CPI inflation targeting including an asset price target.     

Keynesian economics in the twenty-first century1

The Keynesian theory as set out by Keynes embodied an Achilles heel which he himself half understood but chose to ignore. It is also ignored by “post-Keynesians” and “New Keynesians”. The trouble is not in the labour market but in the goods market, where The General Theory, at least up to Chapter 19, definitely assumes perfect competition. But on that assumption the possibility of a Keynesian recession requires that employers behave with highly inconsistent expectations. Once, however, the assumption of perfect competition in the goods market is replaced by imperfect competition or oligopoly, the Keynesian theory re-emerges not only as robust, but also totally relevant to the 21st century.     

Taking the emergent in team emergent states seriously: A review and preview

Team emergent states are properties that develop during team interactions and describe team members' attitudes and feelings (e.g., cohesion). However, these states' emergent nature has largely been neglected, as most studies do not examine the temporality of team phenomena. We review longitudinal studies on team emergent states and demonstrate that a majority of papers reveal their temporal dynamics but offer no universal patterns as to how such states emerge. The review reveals common variables related to temporal dynamics and highlights the importance of studying the development of team emergent states to enhance our knowledge of their causal directions, antecedents, and outcomes. We suggest that future research should clarify the concept of team emergent states, connect theories to research on temporal dynamics, adopt more qualitative approaches to answer “how” and “why” questions, and improve research designs to study meaningful forms of change. Lastly, we present practical implications for the HR field.     

Stability and efficiency from a Neo-Keynesian viewpoint

This paper raises once more the Keynesian challenge of the classical doctrine that an unguided market economy has a natural tendency towards optimal employment of resources. By means of a simple macromodel, we show that if quantity expectations are incorporated into the Walrasian model, then it is no longer generally true that the ‘invisible hand’ leads the economy to Walrasian equilibrium. Instead, it may lead the economy to a kind of Keynesian equilibrium in which the firms' sales expectations constitute a binding constraint on production. Moreover, while Pareto optimum is unstable and hence unattainable in our model, a ‘second-best’ optimum among stable equilibria exists and requires a public sector. Accordingly, a trade-off between efficiency and other policy aims occurs only at tax rates above the positive tax rate in optimum     

基于投入产出结构的中国经济总供给—总需求模型研究

鉴于一般的宏观经济预测模型中缺乏对历史数据反映供需失衡状态的分析,本文构建了一个基于投入产出(IO)分析原理的总供给—总需求(AS-AD)分析框架,以中国1987～2007年投入产出表为基础进行实证分析。结果表明:我国货币政策和财政政策对经济均衡产出水平的影响较小;减税能够改善就业和对外贸易状况,且对劳动者收入改善效果显著;劳动生产率提高是经济增长的有效途径,但需要改善就业和劳动者收入政策措施的配合。     

A Test of U. S. National Economic Policy in the Post-World War II Period

Abstract . This inquiry is an effort to evaluate the macroeconomic performance of the United States economy in the period after the close of World War II in terms of the macroeconomic goals to which national economic policy supposedly had been directed. That is, whether policy achieved full employment, price stability or an adequate rate of growth. Insofar as key indicators can be used as a basis for judgment—and there is, as yet, no scientific basis for measuring how far that reliance can be chanced—it would appear that policy was least successful in attaining full employment with price stability, or full employment, or price stability. In certain infrequent periods, growth seems to have occurred. But was its rate “adequate?” And did it result from policy? Analysis by key indicators may not tell us much, if anything; but it helps to delineate an approach toward policy-monitoring researchers need to cultivate.     

A model of population distribution,traffic congestion,and neighborhood crowding in a circular city

An idealized static equilibrium model of a circularly symmetric city is presented. The model allows one to compute the spatial distribution of residences, given certain simple and plausible assumptions about the “costs” of transport, housing and neighborhood crowding. The model is chosen so as to guarantee that in first approximation, the residential population distribution which would be considered optimal by a perfect planner is identical to the distribution reached in a push-shove, laissez-faire equilibrium. This aspect of the construction is shown to be related in a simple way to the familiar “external diseconomy” situation in which a free resource is allocated among alternative uses by equating average, rather than marginal products. The existence of an infinite class of models in which the associated planner's optimum and laissez-faire equilibria are equivalent follows naturally from the standard theory of the private and social costs of highway congestion. The model leads naturally to exponentially falling population distributions which exhibit an “urban-suburban” dichotomy, to a particular overall city size, and to an optimal allocation of land between transport and residential uses.     

Estimation and recent behavior of urban population and employment density gradients

The monocentric model of urban structure predicts that urban population density declines with distance from the central business district. Using the negative exponential function to approximate the decline, Mills (E. S. Mills, “Studies in the Structure of the Urban Economy,” Johns Hopkins Press, Baltimore, Md. (1972)) estimated population and employment density gradients from 1948 to 1963 for a sample of 18 SMSAs. This paper updates Mills' estimates and examines recent patterns in population and employment suburbanization. The updated series estimated here is obtained using a “corrected” version of Mills' method. The original procedure incorporated a bias which Mills noted and later corrected (E. Mills and K. Ohta, in “Asia's New Giant” (Patrick and Rosovsky, Eds.), The Brookings Institution, Washington, D.C. (1976)). The comparability of the series begun by Mills and extended here is not interrupted, however, because, as Mills suspected, the bias is indeed small provided SMSA data are used. On the other hand, Urbanized Area definitions of metropolitan areas cause the original and corrected versions to yield significantly different results. This finding has implications for the appropriate choice of data for urban studies.     

Beyond National Systems,Towards a ‘Gig Economy’? A Research Agenda for International and Comparative Employment Relations

This journal (Volume 29, Issue 3, 2017) included four review essays that focussed on the 6th edition of the book International and Comparative Employment Relations: National Regulation, Global Changes (Bamber et al. 2016). This article reflects on these essays. It begins to develop a novel multi-scalar analytical framework for comparing employment relations internationally, which includes the influence of the institutional dynamics of industrial sectors and global production networks as well as national systems. It also discusses three aspects of the gig economy. Further it proposes a research agenda that would look beyond Varieties of Capitalism approaches, to embrace a more dynamic and diverse array of regulatory systems, including the gig economy and other developments in the world of work and employment relations.     

All of work? All of life? Reconceptualising work‐life balance for the 21st century

This paper argues that the study of work‐life balance to date has, in the main, adopted a restricted conception of both “work” and “life”, which does not take account of recent developments in life worlds, working arrangements and employment relationships. “Life” has hitherto been viewed as largely comprising caring activities for dependent children, whereas “work” has been premised largely on a traditional model of work, characterised by full‐time, permanent employment with one employer and a conventional understanding of what work involves. This means that extant research and theory only provides a partial view of the work‐life needs and experiences of the workforce. In the paper, we propose extending conceptions of both work and life to incorporate different life worlds and social groups and different working arrangements and employment relationships.     

Professional forecasters and real-time forecasting with a DSGE model

This paper analyses the real-time forecasting performance of the New Keynesian DSGE model of Galí, Smets and Wouters (2012), estimated on euro area data. It investigates the extent to which the inclusion of forecasts of inflation, GDP growth and unemployment by professional forecasters improve the forecasting performance. We consider two approaches for conditioning on such information. Under the “noise” approach, the mean professional forecasts are assumed to be noisy indicators of the rational expectations forecasts implied by the DSGE model. Under the “news” approach, it is assumed that the forecasts reveal the presence of expected future structural shocks in line with those estimated in the past. The forecasts of the DSGE model are compared with those from a Bayesian VAR model, an AR(1) model, a sample mean and a random walk.     

The Taylor principle fights back,Part II

The existing literature holds that the Taylor principle often leads to indeterminacy in New Keynesian models that allow for capital accumulation and limited asset market participation. This conclusion is special, however, to the case of continuous full employment. When the assumption of perfect wage flexibility is relaxed very slightly so that the labor market clears quickly but not instantaneously, determinacy is the norm. The threat of indeterminacy is limited to a tiny, irrelevant corner of the parameter space where the elasticity of labor supply is unusually high and real wage adjustment is unbelievably fast. Everywhere else, the Taylor principle guarantees a unique rational expectations equilibrium. The dramatic difference in results reflects the sensitivity of the monetary transmission mechanism to the speed of adjustment in the labor market.     

Preference revelation games and strong cores of allocation problems with indivisibilities

This note considers the equilibrium outcomes of the preference revelation games in the general model of indivisible good allocation introduced by [Sönmez, T., 1999. Strategy-proofness and essentially single-valued cores. Econometrica 67, 677–689]. We adopt the concepts of coalitional equilibria and cores which are both defined in terms of the weak deviation or blocking by a prescribed class of admissible coalitions. We prove that if the solution which induces preference revelation games is individually rational and Pareto optimal and the class of admissible coalitions is “monotonic,” then the set of coalitional equilibrium outcomes coincides with the core. And we point out that the preceding analysis in the context of marriage problems [Gale, D., Shapley, L., 1962. College admissions and the stability of marriage. American Mathematical Monthly 69, 9–15] is hardly extended to the general model.     

The Disequilibrium Theory of Changes in Total Economic Activity

Abstract . It is widely taught that national product departs from, but returns toward, an “equilibrium” level. Return from sub-equilibrium, it is believed, involves depleting inventories; return from super-equilibrium involves building them up; in both cases, at a diminishing rate. Observable product and observable aggregate stocks of goods, however, usually rise and fall together; they do not change in opposite directions, as implied. Stocks are not large enough to support the supposed depletion at low income levels. “Intended” changes contrary to the actual changes are not documented. The disequilibrium theory does not promote understanding of historical cycles in product.     

DAMN THE RULES, IT'S A PARALLEL UNIVERSE!

Even though Keynesian policy has shown itself ineffective in sustaining full employment without inflation, bogus panaceas have again been rolled out, by politicians and economists seeking to ameliorate the aftermath of excessive credit. Keynesian interventions can only impair readjustments and delay recovery.     

Learning a population distribution

This paper introduces a dynamic Bayesian game with an unknown population distribution. Players do not know the true population distribution and assess it based on their private observations using Bayes׳ rule. First, we show the existence and characterization of an equilibrium in which each player׳s strategy is a function not only of the player׳s type but also of experience. Second, we show that each player׳s initial belief about the population distribution converges almost surely to a “correct” belief.     

Markets with heterogeneous beliefs: A necessary and sufficient condition for a trader to vanish

What does it take to survive in the market? Previous literature has proposed sufficient conditions for a trader to vanish, which depend on pairwise comparisons of traders’ discounted beliefs. We propose a novel condition that focuses on the ratio of traders’ discounted beliefs and (approximate) equilibrium prices. Unlike existing conditions, ours is both necessary and sufficient for a trader to vanish and delivers the exact rate at which vanishing traders lose their consumption shares. As an application, we analyze the performance of two intuitive behavioral strategies: the “Follow the Leader Strategy” that prescribes mimicking the beliefs of the most successful trader, and the “Follow the Market Strategy” that prescribes to use beliefs which coincide with the state price density. Further, we show that the relative performance of vanishing traders cannot be studied in isolation. Our analysis highlights an intuitive point obscured by the existing conditions: trading in financial markets is qualitatively different from bilateral trading.     

Credit market disequilibrium in Poland: Can we find what we expect?: Non-stationarity and the short-side rule

This paper presents an empirical investigation of the disequilibrium hypothesis on the Polish loan market in the 1990s. Using data over this period of rapid and sustained transition, we estimate a disequilibrium model with a standard maximum likelihood method. However, the estimates are highly counter-intuitive as regards the timing of the identified regimes. We show that the gap between the econometric evidence and the expected results may stem from the phenomenon of stochastic non-stationarity in a disequilibrium setting based on the short-side rule. We find that the omission of one non-stationary variable of the cointegrating space or the absence of a “structural” cointegrating relationship in one or both regimes lead to a spurious configuration. In such a case, the wrong use of the standard likelihood function, derived under the stationarity assumption, may lead to non-convergent estimates of structural parameters and, hence, to an erroneous identification of the regimes. Therefore, as a first approach to this problem, we estimate a disequilibrium model with stationary data, and identify the disequilibrium as an excess of quantities of new loans supplied (or demanded) on the market at time t. The empirical results are then robust and economically founded and correspond to the set and the timing of expected regimes.
