Is the Labour Market Adjustment in Poland Surprising?

Abstract. On the basis of the brief review of developments in employment and wages in Poland during the stabilization program in 1990, this paper tries to provide critical comments on the two often expressed opinions: that the fall in employment was surprisingly small compared to the fall in output, and that the tax-based incomes policy played a major role in forcing a huge drop in real earnings. It is argued that the actual proportions of the fall in output and employment were in line with specific features of the “overheated” shortage economy, which existed prior to the stabilization program. Since wages were not a “nominal anchor” for most of 1990, other reasons for the astonishing downward flexibility of real wages are analyzed. It is suggested that during the labour market adjustment, the rational strategy of employees was to accept a large, real wage cut in exchange for keeping their employment. Contrary to widespread opinion, it might also be argued that incomes policy, in a short and medium run, will play a much more important role in containing wage pressure than it has until now.     

Is Imperfect Competition in the Product Market Relevant for Labour Markets?

Recent research in macroeconomics emphasises the importance of imperfect competition in the product market for labour market outcomes. We investigate one aspect of this issue by specifying a dynamic labour demand model where firms face different degrees of competition in the product market and test its predictions for 299 US manufacturing industries. We find that the long-run equilibrium level of industry employment as well as the speed of labour demand adjustment decreases with market power. Our results imply that imperfect competition in the product market explains part of the observed labour market rigidities and also sheds new light on two “stylized facts” in industrial organisation, the observation of procyclical movements in productivity and price–cost margins in concentrated industries.     

Regional Labour Market Adjustment: Are Positive and Negative Shocks Different?

This paper analyses regional labour market adjustment in the Finnish provinces during 1971–96. It investigates the interrelations of employment, unemployment and labour force participation to examine how a change in labour demand is adjusted to. The study questions the usual assumption that positive and negative shocks evoke similar adjustment processes. Instead, we test for the possibility that the effects of positive and negative shocks are asymmetric. The analysis reveals that there is little asymmetry in the adjustment to region‐specific labour demand shocks, but adjustment to total (region‐specific plus common component) shocks displays more asymmetry. The region‐specific component of a labour demand shock has short‐lived effects on unemployment and participation, and its effect on employment is very small but permanent [persistent?]. Initially, most of the fall in employment is absorbed by the unemployment and participation rate, but after a few years migration plays a larger role in the adjustment process.     

Entreprise Management in the USSR: is there a Productivity Drive?*

Abstract. According to some neo-institutional economists, the trade-off of perestroika is between the benefits of solving economic problems via institutional changes and the costs of upsetting the nomenklatura. The “sub-institutional” analysis shows instead a series of organizational adjustments of the productive system that can render this dilemma less pressing, provide Western financial aid increases. This aid will ease the social and political tensions of the transition much more than helping the start of a productivity drive in Soviet firms.     

The Wages of Sin? Illegal Drug Use and the Labour Market

We use data from the British Crime Survey (BCS) to analyse the relationship between illicit drug use and labour market outcomes for a sample of men and women aged 16–25. In using these data we highlight a serious design flaw in the BCS questionnaire structure that presents a serious barrier to statistical modelling of drug use at the individual level. We propose a simple way of overcoming this problem and proceed to estimate a model of occupational attainment jointly determined with unemployment and current drug use, conditional on past drug use. Separating the commonly abused drugs into a ‘hard’ and ‘soft’ category, we find that past hard drug use has a significant positive association with current unemployment, but find no significant association between past hard or soft drug use and occupational attainment. We also find no significant association between current drug use and attainment, although we observe that current drug use is associated with current unemployment.     

Do Interactions between Finance and Labour Market Institutions Affect the Income Distribution?

This article analyses the linkages between financial development, labour market institutions and market income inequality for 18 Organisation for Economic Co‐operation and Development countries over the 1980 to 2012 period. With the help of a dynamic panel data model with an interacted term, one crucial contribution of this article is to analyse the interacted impact of labour market institutions (i.e. union density and employment protection legislation) on the one hand and financial development on the other hand on the income distribution. Our results indicate that changes in the financial/credit and labour market regulation affect the income distribution. Estimates of the marginal effects show that by increasing labour market regulation one also weakens the impact of the flexibilization in the financial/credit market on the increase in income inequality.     

Are you on the right track?

Is there a physician union in your future?

Physician unions are in the news. Patient management and patient care decisions are increasingly being taken out of the hands of physicians and put into the hands of "The Suits." To take their case for a return to physician-driven patient care to the people, some physicians are joining unions. Some are even collectively bargaining for salary and other issues that are historically more closely associated with unions. The simple fact is that physician unions exist and the number of physicians joining them is expected to increase. What are the pros and cons of unionization? What motivates physicians to join unions, and what potential negative and positive factors are associated with physician unionization? This article reviews the pros and cons and the issues related to physician unions, for physicians attempting to answer the question, "Is there a union in my future?"     

Efficiency and stock performance of EU banks: Is there a relationship?

The purpose of this paper is to examine whether the stock performance of EU listed banks is related to their efficiency. Our sample consists of 171 banks operating in 15 EU markets over the period 2002–2006. First, we use stochastic frontier analysis to estimate the cost and profit efficiency of banks, while controlling for environmental factors. Then, we investigate if changes in profit and cost efficiency are reflected in changes in stock prices. Our results indicate that the change in profit efficiency has a positive and significant impact on stocks prices; however, there is no relationship between changes in cost efficiency and stock returns.     

Mismatch in the West German Labour Market? Economic Restructuring and Unemployment in the 1980s*

Abstract. The paper briefly investigates theoretical arguments for mismatch unemployment; it presents a vacancy-unemployment curve for Germany and investigates various reasons for outward shifts of the curve. Both variables, unemployment and vacancies, are decomposed into flows and duration to identify the underlying processes of these shifts. The analysis of the components with the help of change-duration curves shows adverse trends for unemployment and vacancies over the business cycles. Unemployment duration has increased while vacancy duration has decreased. Mismatch in the labour market can therefore hardly be blamed to have been an obstacle for economic expansion in the German economy during the 1980s. Persistently high unemployment in Germany has to be interpreted as a hysteresis process which was driven by macroeconomic policies, increasing labour supply and restructuring imbedded in the German institutional framework.     

Is there a distinctive MENA model of corporate governance?

This study explores the diversity of corporate governance practices in the MENA region, with particular emphasis on Saudi Arabia and Egypt. Interviews with senior managers find that the state, foreign investors and large family groups act as monitors of corporations in both countries, whereas the role of institutional investors and other shareholder activist groups is minimal. Ownership was more concentrated in Egypt than in Saudi Arabia, particularly in family firms. However, control is firmly in the hands of dominant shareholders even when ownership concentration is not high enough to merit such control and boards are dominated by majority shareholders. The high levels of concentrated ownership and control, and the low levels of disclosure and transparency, clearly differentiates the corporate governance system in the region from that in Anglo-American countries while the importance of state and family shareholders reflects characteristics of organisation and control found in many developing countries, predominantly those in Asia. However, it remains premature to speak of a unique MENA model of corporate governance.     

Is the Swiss Labor Market Segmented? An Analysis Using Alternative Approaches

Abstract. In this paper, three common empirical methods encountered in the segmentation literature are used in order to establish whether or not the Swiss labor market is segmented: (i) a hierarchical cluster analysis; (ii) a switching model with unknown regime; and (iii) an analysis of low‐wage mobility with a bivariate probit model with endogenous selection. According to method (i), segmentation can hardly be observed. Method (ii) shows that the Swiss labor market is dualistic in nature. Method (iii) reveals that a certain degree of persistence exists in low‐wage jobs. Whether or not the Swiss labor market is segmented thus depends on the choice of method, i.e. on the definition and understanding of segments. In any case, none of the methods used in this study point to the existence of a large and well‐defined secondary segment.     

Parameters of a Dose‐Response Model Are on the Boundary: What Happens with BMDL?

It is well known that, under appropriate regularity conditions, the asymptotic distribution for the likelihood ratio statistic is χ². This result is used in EPA's benchmark dose software to obtain a lower confidence bound (BMDL) for the benchmark dose (BMD) by the profile likelihood method. Recently, based on work by Self and Liang, it has been demonstrated that the asymptotic distribution of the likelihood ratio remains the same if some of the regularity conditions are violated, that is, when true values of some nuisance parameters are on the boundary. That is often the situation for BMD analysis of cancer bioassay data. In this article, we study by simulation the coverage of one- and two-sided confidence intervals for BMD when some of the model parameters have true values on the boundary of a parameter space. Fortunately, because two-sided confidence intervals (size 1–2α) have coverage close to the nominal level when there are 50 animals in each group, the coverage of nominal 1−α one-sided intervals is bounded between roughly 1–2α and 1. In many of the simulation scenarios with a nominal one-sided confidence level of 95%, that is, α= 0.05, coverage of the BMDL was close to 1, but for some scenarios coverage was close to 90%, both for a group size of 50 animals and asymptotically (group size 100,000). Another important observation is that when the true parameter is below the boundary, as with the shape parameter of a log-logistic model, the coverage of BMDL in a constrained model (a case of model misspecification not uncommon in BMDS analyses) may be very small and even approach 0 asymptotically. We also discuss that whenever profile likelihood is used for one-sided tests, the Self and Liang methodology is needed to derive the correct asymptotic distribution.     

Can there be a domain-specific knowledge base in HRD? Reflections on the Lille symposium

A conversation recently began amongst senior human resource development scholars from around the world that focused on the prospects for theory development in human resource development (HRD). The opening event in the form of a panel discussion was held at the European HRD conference in Lille, France, in May 2008. This article summarizes and discusses contributions made by the panel participants.     

Are there Gender Differences in the Ethics Judgments of Marketing Managers?

This study found that moral reasoning predicts intention to act in an ethical dilemma, but that this behavior is not modified by gender differences. Fishbein and Ajzen’s Reasoned Action model was used to predict intention to act in ethical dilemmas, while the Kohlberg and Gilligan paradigms of moral reasoning were introduced as exogenous variables. The theory of reasoned action model was found to be a good predictor of intention as hypothesized. Suggestions for further research are included. This revised version was published online in July 2006 with corrections to the Cover Date.     

How Do Policies Affect the Exit Rate out of Unemployment? Disentangling Job Creation from Labour Market Frictions

This paper assesses the effects of labour market policies on the unemployment outflow rate while disentangling two channels, namely labour market tightness and employer–employee matching efficiency. Using a sample of 11 OECD countries over the period 1985–2007, we treat the endogeneity of market tightness with business cycle shocks and the tax wedge as instruments. We find that the replacement rate of unemployment benefits, Active Labour Market Policies as well as the tax wedge in countries with poorly representative unions, have a significant, robust, and large impact on market tightness. Employment protection has a negative but small impact on matching efficiency. Overall, policy effects appear to be mostly channeled through market tightness and job creation.     

Are crowds on the internet wiser than experts? The case of a stock prediction community

According to the “Wisdom of Crowds” phenomenon, a large crowd can perform better than smaller groups or few individuals. This article investigates the performance of share recommendations, which have been published by members of a stock prediction community on the Internet. Participants of these online communities publish buy and sell recommendations for shares and try to predict the stock market development. We collected unique field data on 10,146 recommendations that were made between May 2007 and August 2011 on one of the largest European stock prediction communities. Our results reveal that on an annual basis investments based on the recommendations of Internet, users achieve a return that is on average 0.59 % points higher than investments of professional analysts from banks, brokers and research companies. This means, that on average, investors are better off by trusting the crowd rather than analysts. We furthermore investigate how the postulated theoretical conditions of diversity and independence influence the performance of a large crowd on the Internet. While independent decisions can substantially improve the performance of the crowd, there is no evidence for the power of diversity in our data.     

The Problem Is Fraud: Is the Solution Government Bounties?

Whistle‐blowing is the disclosure of organizational wrongdoing by internal or external parties either within the organization or publicly to outsiders who may be able to effect a positive change in action or activities. Organizations have been encouraged, especially since the passage in 2002 of the Sarbanes–Oxley Act, to establish a culture in which whistle‐blowing is seen as a positive mechanism to correct misconduct rather than a negative attack. This article addresses (1) whistle‐blowing in relationship fraud and (2) governmental “bounties” paid to persons who are willing to provide knowledge of organizational transgressions. The fraud could occur through a variety of mechanisms but, regardless of the fraud's cause, the long‐run result will be harmful to the organization, its employees, its customers, and the society in which the organization operates. The question is whether bounties are the most effective means by which to reduce the harm created by fraud.     

Is there any polynomial upper bound for the universal labeling of graphs?

A universal labeling of a graph G is a labeling of the edge set in G such that in every orientation \(\ell \) of G for every two adjacent vertices v and u, the sum of incoming edges of v and u in the oriented graph are different from each other. The universal labeling number of a graph G is the minimum number k such that G has universal labeling from \(\{1,2,\ldots , k\}\) denoted it by \(\overrightarrow{\chi _{u}}(G) \). We have \(2\Delta (G)-2 \le \overrightarrow{\chi _{u}} (G)\le 2^{\Delta (G)}\), where \(\Delta (G)\) denotes the maximum degree of G. In this work, we offer a provocative question that is: “Is there any polynomial function f such that for every graph G, \(\overrightarrow{\chi _{u}} (G)\le f(\Delta (G))\)?”. Towards this question, we introduce some lower and upper bounds on their parameter of interest. Also, we prove that for every tree T, \(\overrightarrow{\chi _{u}}(T)={\mathcal {O}}(\Delta ^3) \). Next, we show that for a given 3-regular graph G, the universal labeling number of G is 4 if and only if G belongs to Class 1. Therefore, for a given 3-regular graph G, it is an \( {{\mathbf {N}}}{{\mathbf {P}}} \)-complete to determine whether the universal labeling number of G is 4. Finally, using probabilistic methods, we almost confirm a weaker version of the problem.
