Hollowing out of middle-pay jobs in Ohio: An exploratory analysis

Hollowing out is a term that refers to the decline in the share of middle-pay and middle-skilled jobs relative to low-pay and high-pay jobs. This study employs county-level occupational data at the place of employment to document hollowing out of middle-pay jobs across regions in Ohio. The county-level data with occupational information allow us to study how regions' economic heterogeneity contributes to the decline of middle-paying jobs in Ohio over the 2001–2019 period. Of 88 counties in Ohio, 77 counties experienced declines in the shares of middle-paying jobs. On average, Appalachian Ohio counties experienced higher hollowing out rates than other counties. We found that the hollowing out of middle-paying jobs in Ohio is associated with the declines in the shares of manufacturing and mining jobs.     

Offshoring of routine tasks and (de)industrialisation: Threat or opportunity—And for whom?

Offshoring, or overseas sourcing of routine tasks, generates efficiency gains that benefit consumers and workers with skills similar to those whose very jobs are threatened by offshoring. Essentially, the interaction between offshoring, footloose capital and agglomeration economies locks the comparative advantage of advanced nations in complex or strategic functions while labour services in ‘routine’ tasks, the coordination of which is easily codified, are provided by low-wage developing nations through the fibre optic cable. In this framework, the partial-equilibrium view that offshoring is necessarily detrimental to workers in advanced nations is misguided because the implicit counterfactual—that keeping the off-shored jobs would have no macroeconomic impact on the economy—is not warranted. In addition, inasmuch as routine tasks create few positive feedbacks, trade in tasks can be an impediment to income convergence, unlike trade in goods. In short, this paper qualifies the views that offshoring hurts workers in the North and accelerates income convergence between the North and the South.     

Looking across borders: A test of spatial policy interdependence using local government efficiency ratings

Spatial patterns in (local) government taxation and spending decisions have received a lot of attention. Still, the focus on taxation or expenditure levels in previous studies may be incomplete. Indeed, (rational) individuals are likely to consider the level of spending on (or taxation for) public goods provision simultaneously with how much public goods they actually receive—thus assessing the ‘price/quantity’ of government policies. Therefore, the present paper argues that incumbents may want their ‘price/quantity’ ratio to be close to that in neighbouring regions. Analysing Flemish local governments' efficiency ratings for the year 2000 (which relate total spending to the quantity of locally provided public goods), we confirm the existence of neighbourhood effects in local government policies.     

New highways as economic development tools: An evaluation using quasi-experimental matching methods

Stimulating economic growth and development in rural and economically lagging regions is the goal of several federal and state highway programs. This paper examines the effectiveness of highway investment as an economic development tool. A quasi-experimental matching method is used to examine the effects of interstate highways on counties which obtained links during the period 1963–1975 or are in close proximity to these newly linked counties. The results show that the beneficiaries of the interstate links in terms of economic growth are interstate counties in close proximity to large cities or having some degree of prior urbanization, such as a city with more than 25,000 residents. Rural interstate and off-interstate counties exhibit few positive effects.     

The latin model of welfare: Do ‘insertion contracts’ reduce long-term dependence?

This paper aims to present an assessment of the welfare policies implemented in most South European countries. Welfare programs in these countries try to combine a basic level of economic protection and measures favoring life and labor skills (‘insertion benefits’) of low-income households. We focus on a specific program set up with the twofold strategy of cash and ‘insertion benefits’ (Madrid's IMI) and, more precisely, on the so-called ‘insertion projects’, consisting in a gradual mix of job search assistance, training and subsidized jobs. We evaluate the effects of these ‘insertion projects’ on welfare recidivism and the duration of off-welfare spells using propensity score-matching methods. Our results suggest that propensity score estimators appear to reduce selectivity due to non-random participation. Both recidivism rates as well as the duration of off-welfare spells suggest potentially successful interventions.     

Women in blue collar and related occupations at the end of the millennium

Electricians, truck drivers, fire fighters, and sewing machine operators are some of today’s blue collar workers. Despite the steady decline in manufacturing, labor force projections suggest that blue collar work will continue to be an important source of employment for women as well as men. Equal opportunity, however, has eluded women in these occupations. Higher paying, more skilled jobs are held by men, while women remain concentrated in less skilled, lower paying jobs. Problems are identified and solutions suggested for integrating women into the nontraditional jobs, as well as for improving the wages and working conditions in traditional jobs.     

What is behind the real appreciation of the accession countries’ currencies?: An investigation of the PPI-based real exchange rate

In the paper, we calculate real equilibrium exchange rates (EER) for EU accession countries and compare these with the actual exchange rate movements since the mid-1990s. The real equilibrium exchange rates are derived from models of macroeconomic balance and tested for econometrically. It is found that productivity increases can be regarded as one source of the observed PPI-based real appreciation of the accession countries’ currencies. These productivity gains experienced in the process of economic catch-up imply an increased capacity to produce high-quality export goods and are a key driving force of exports. To a large extent real appreciation can, therefore, be viewed as an equilibrium phenomenon.     

The spatial structure of production with a leontief technology – II: Substitute techniques

The structure of the optimal spatial pattern of production is studied when there are dependencies among production units which can be described by a Leontief technology with substitute techniques, and when there is a single marketplace of final demand, the CBD. Transportation cost is proportional to distance. The various goods are produced in rings. There are a finite number of patterns in which these rings are arranged, and they can be obtained by a finite algorithm. The particular pattern depends on the final demand. Hence there is no ‘non- substitution’ theorem. ‘Reswitching’ of techniques can occur, that is, in an optimal pattern a technique may be operated at large and small distances from the CBD, but not at intermediate distances; this contradicts prevailing beliefs about optimal capital/land profiles.

Occupational gender segregation Trends and explanations

This article examines recent research on occupational segregation by gender. It reviews and evaluates statistical approaches to measuring the extent to which women are disproportionately represented in “women’s jobs” and men in “men’s jobs.” By combining the findings of a number of studies, it traces the changes in the extent in occupational segregation from the end of the nineteenth century until 1995, and the forms and extent of gender segregation in occupations cross-nationally. In addition to the trends, this article considers the consequences of segregation to women. Finally, current explanations for occupational segregation are analyzed and assessed by considering the empirical data on occupational segregation.     

About inheritance distribution

In this work, we propose two axiomatic procedures to distribute an inheritance based on monetary compensations. In a cooperative context, the differences among the agents’ evaluations of the goods are used to increase everyone’s participation. When the goods’ valuations are heterogeneous each agent gets much more than 1/n of the value he believes the inheritance has.The two procedures are characterized by three criteria, namely: money preservation, Pareto optimality, and a certain kind of proportionality. The difference of the procedures is determined by the kind of proportionality used.     

Industry Mix, Wages, and the Divergence of County Income in Pennsylvania

Per capita incomes have diverged across Pennsylvania counties. County incomes may differ because of differences in industrial structures and because of differences in earnings within industries; a county may have a below-average income because its industry mix is comprised of low paying jobs or because county jobs pay low wages compared to the same jobs in other counties. A procedure developed by Hanna (1951) is utilized to separate income differences into these two components by constructing two counterfactual incomes for each county. The handful of high-income counties in Pennsylvania have favorable wages while the counties with incomes below the state average, although with employment mixes comparable to the overall state mix, tend to have workers who receive low wages relative to the state industry average. Wages are low in the relatively poor counties due to less investment in physical and human capital.     

Patents for genetic inventions: a tool to promote technological advance or a limitation for upstream inventions?

Today's conventional wisdom among economists and lawyers is heavily weighted toward the proposition that strong and broad patent rights are conducive to economic progress. Concerns have been raised as to the extent to which strong patent rights could build up barriers to follow-up research and thus hinder technological advance. This poses a number of difficulties particularly in the area of genetics with respect to the scope of protection and the definition of what is patentable. This article considers the problems of ‘anti-commons’, limitations for upstream inventions, patent thickets and royalty stacking with licenses for genetic inventions. A survey of 53 biotechnology companies in Switzerland builds the empirical basis of the investigation. The survey results confirm that the concepts of ‘anti-commons’, ‘patent thickets’ and ‘royalty stacking’ are indeed relevant. However, they are not highly relevant for the Swiss biotechnology industry from an economic point of view. A broad research exemption combined with a protection limited to concrete disclosure functions of DNA patents and compulsory licensing arrangements are considered as feasible remedies for overcoming certain difficulties with gene patents.     

Economics of personnel and human resource management

The new economics of personnel and human resource management is analysed, including its current prominence as well as its historical antecedents. The economic paradigm as applied to personnel and human resource economics is illustrated through a variety of examples in the personnel area. These involve economic phenomenon (e.g., fixed hiring costs, asymmetric information, option values) highlighting their implications for personnel issues, as well as personnel phenomenon (e.g., deferred compensation, pensions, mandatory retirement) highlighting their economic rationale. Other phenomenon that otherwise seem difficult to explain or paradoxical are analysed including: superstar salaries; long-hours and overtime coexisting with unemployment and underemployment often within the same organisation; the reluctance of seemingly risk averse workers to accept small wage cuts to avoid the possibility of a layoff; the payment of fringe benefits that may not be valued by many employees; the “regular” hiring of temporary workers when permanent workers are available; egalitarian pay structures and fairness in compensation; the persistent reporting of vacancies on the part of firms but a reluctance to raise wages to fill those vacancies; the use of piece rates in some jobs and salary structures that are based on relative ranking of workers in other jobs; and tenure or “up-or-out” rules where people who are not promoted are required to leave rather than work for lower pay. The concluding section focuses on elements that are common across these applications.     

Multiple equilibria in two-sector monetary economies: An interplay between preferences and the timing for money

In this paper, we study the occurrence of local indeterminacy in two-sector monetary economies. We consider a general MIUF model with two alternative timings in monetary payments: the Cash-In-Advance timing, in which the cash available to buy goods is money in the consumers’ hands after they leave the bond market but before they enter the goods market, and the Cash-After-the-Market timing, in which agents hold money for transactions after leaving the goods market. We consider three standard specifications of preferences: the additively separable formulation, the Greenwood–Hercovitz–Huffman (GHH) (Greenwood et al., 1988) formulation and the King–Plosser–Rebelo (KPR) (King et al., 1988) formulation. First, we show that for all the three types of preferences, local indeterminacy occurs under the CIA timing with a low enough interest rate elasticity of money demand. Second, we show that with the CAM timing, although determinacy always holds under separable preferences, local indeterminacy can occur with GHH and KPR preferences. We thus prove that compared to aggregate models, two-sector models provide new rooms for local indeterminacy when non-separable standard preferences are considered.     

The case for comparable worth

Traditional nondiscrimination efforts focus on women’s access to jobs and on equal pay for the same work. Comparable worth adds a third strategy-policies that ensure that jobs do not pay less because they are filled by women. I review evidence of this discrimination. I describe job evaluation, which can be used to correct it, while preserving a large role for market forces. U.S. workers have no protection from this type of discrimination. I consider arguments raised against comparable worth. The claim that antidiscrimination policies are unnecessary because discrimination is eroded by competitive forces fails to recognize the sluggishness of this response. The argument that barriers to entry are the real problem ignores evidence that cultural devaluation affects wage-setting even absent hiring discrimination. Arguments about undesirable side effects apply with equal force to most regulation. I conclude that comparable worth deserves support.     

Interregional tax competition and intraregional political competition: The optimal provision of public goods under representative democracy

This paper explores the implications of the interaction between interregional tax competition and intraregional political competition for the optimal provision of public goods under representative democracy à la (Osborne and Slivinski, 1996) and (Besley and Coate, 1997). As an extension of Hoyt’s (1991) finding that intensified tax competition is always harmful and aggravates the extent to which public goods are undersupplied in a region, we show that intensified tax competition can be beneficial if political as well as tax competition is considered. In particular, we identify plausible conditions under which (i) there is an optimal intensity of tax competition such that the interaction between interregional tax competition and intraregional political competition will result in the optimal provision of public goods and (ii) intensified tax competition will be beneficial if and only if the degree of tax competition is less than this optimal intensity.     

Optimal property taxation in the presence of interregional capital mobility

A single region's optimal property tax policy is examined in a model with interregional capital mobility. In this model, property taxation is used to finance local public expenditures. Different tax rates may be imposed on property used to produce goods which are traded between regions and property used to produce nontraded goods (e.g., residential property). The key determinants of the difference between the optimal tax rates are identified, and it is argued that there exists a bias towards relatively low tax rates on property used to produce traded goods. The role of labor mobility is also investigated.     

The influence of seller learning and time constraints on sequential bargaining in an artificial perishable goods market

This paper investigates the formation of prices in a perishable goods market where agents bargain repeatedly through pair-wise interactions. After extensive field observations, we chose to focus on two aspects that seem important to actors of this market: the passage of time and update in judgement when gathering information. The main feature of the market is that a seller bargaining with a buyer has incomplete information about buyer's willingness to pay and is not sure how her trading partner will evaluate an offer or compare it with other options. On the other hand, buyers have limited time to look for goods and cannot meet all possible sellers before making a decision. Hence agents cannot calculate the best price to offer but receive information through limited interactions, and use this information to choose their actions.An agent-based model was built to represent a framework that mimics the observed market institution and where agent's possible behaviors and learning was made as consistent as possible with gathered data. Simulations were run, first for sensitivity analysis concerning main parameters, then to test the dependance of agents’ learning to (a) the time buyers can spend on the market and (b) the frequency of update in learning by sellers. To validate the model, features produced by the simulated market are compared to the stylized facts gathered for negotiation about four goods. We reproduce the main features of the data on the dynamics of offers, transaction prices and agents’ behavior during the bargaining phases.
