Subsidizing low-skilled jobs in a dual labor market

We introduce a matching model that allows for classical and frictional unemployment. The labor market is dual featuring low-skilled and high-skilled workers and simple and complex jobs. Simple jobs pay a minimum wage, while wages in the complex jobs are determined by Nash bargaining. Opportunities for low-skilled workers are limited to simple jobs; while high-skilled unemployed can apply for both types of jobs, and thereby can accept to be downgraded. We analyze the outcomes of simple job subsidy policies assuming that government budget is balanced through taxes on occupied workers. We first give conditions for the existence and uniqueness of a steady-state equilibrium and we then analyze the effects of different fiscal instruments. We show that in this set-up, increasing simple job subsidies does not necessarily reduce low-skilled unemployment or unemployment spells. By introducing heterogeneous skills and possible downgrading of the high-skilled workers, we show that the effectiveness of such policies in reducing the classical unemployment is decreasing. In fact, any additional classical unemployed re-entering the job market is accompanied by an increasing number of high-skilled workers downgrading to low-skilled jobs. We calibrate the model on French labor market data. It is found that for five low-skilled workers leaving classical unemployment, two high-skilled workers are downgraded.     

Informality in developing economies: Regulation and fiscal policies

This paper proposes a unified theoretical framework where formal and informal firms coexist and face the same type of product and labor market imperfections: they have monopoly power in the goods market, they are subject to matching frictions in the labor market, and wages are determined by bargaining between large firms and their workers, through either individual or collective bargaining. Our model matches the main stylized facts on informality for developing countries and appears to be a good candidate for policy analysis. In this framework, we study the impact on informality, wages and unemployment of policies that may be used to reduce informality. We consider changes in product market regulation (PMR) and in two types of fiscal policies, labor taxes and formality enforcement. We find that lessening PMR decreases informality and unemployment simultaneously, indicating that there is not necessarily a tradeoff between informality and unemployment. The tradeoff appears when fiscal policies are used, though. Moreover, the impacts of PMR on unemployment and on wages are larger under collective than individual bargaining. With respect to wage inequality, lessening PMR reduces it, while lower taxes tend to increase the formal sector wage premium.     

Are unemployment rates in OECD countries stationary? Evidence from univariate and panel unit root tests

This paper revisits the dynamics of unemployment rate for 29 OECD countries over the period of 1980–2013. Numerous empirical studies of the dynamics of unemployment rate are carried out within a linear framework. However, unemployment rate can show nonlinear behaviour as a result of business cycles or some idiosyncratic factors specific to labour market (Cancelo, 2007). Thus, as a testing strategy, we first perform Harvey, Leybourne, and Xiao (2008) linearity unit root test and then apply the newly ESTAR nonlinear unit root test suggested by Kruse (2011). This test has higher power than conventional unit root tests when time series exhibits nonlinear behaviour. Our empirical findings provide significant evidence in favour of unemployment rate stationarity for 25 countries. For robustness purpose, we have also used panel unit root tests without and with structural breaks. The empirical results show that unemployment hysteresis hypothesis is strongly rejected, when taking into account the cross-sectional and structural break assumptions. Thus, unemployment rate is expected to return back to their natural levels without executing any costly macroeconomic labour market policies by the OECD’s governments.     

Long-term Unemployment and the Labour Market: some further results

In a previous Briefing Paper we discussed the current high rate of long-term unemployment. We described the process by which the ratio of long-term unemployment to total unemployment was determined and suggested some explanations for the rapid rise in long-term unemployment since 1980. We also investigated the role of long-term unemployment in shifting the relationship between unemployment and vacancies. In this Briefing Paper we extend our study to consider the relationship between unemployment and inflation. In particular we discuss the apparent failure of high unemployment to affect the growth of real wages. Finally we compare some policies for reducing unemployment.     

Evaluating the value of an entrepreneurial city with a spatial hedonic approach: A case study of London

This study assesses the value of a city by using the housing price function with a geographically weighted regression model, including various social, economic, and environmental factors. To assess these values, various specific data scores—such as those related to ethnic groups, green areas, crime rates, education, unemployment rates, number of entrepreneurs, and environmental quality—were considered in a case study of London. The results indicate that some variables such as time to city center and entrepreneurship have a positive impact on the local areas’ value in London, as shown by housing prices, while those related to unemployment have a negative impact. Moreover, although the London city center has benefitted more in terms of value than its outskirts have, a few specific policies related to startups and entrepreneurship have succeeded in connecting these areas to existing companies and entrepreneurs. In general, large cities may be better equipped to promote such startup and entrepreneurship policies under local industry plans for future development.     

The economic consequences of environmental regulation in China: From a perspective of the environmental protection admonishing talk policy

Environmental regulation may lead to undesired economic consequences. China has tightened its environmental policies to deal with severe environmental pollution in recent years, but existing studies pay little attention to the economic consequences of China's environmental policies. Using the panel data of 211 prefecture‐level and above cities in China from 2003 to 2016, we for the first time estimate the economic impact of the environmental protection admonishing talk (EPAT) policy, a newly implemented environmental regulation policy in China. We use the difference‐in‐differences strategy to identify the economic effects of the EPAT policy combined with the propensity score matching method to control a potential selection problem. The results show that a relative decline occurs in gross domestic product per capita in target cities after the implementation of the EPAT, and the negative impact is exerted on the secondary industry rather than the tertiary industry. Furthermore, we find that target cities respond to the environmental protection requirements of higher authorities through a one‐size‐fits‐all approach of limiting the production activities of industrial enterprises. Meanwhile, the EPAT policy does not improve environmental efficiency. Such findings are instructive for policymakers who need to trade off economic welfare and environmental quality when formulating and implementing new environmental policies.     

The environmental and macroeconomic effects of socially responsible investment

We analyze the effects of socially responsible investment and public abatement on environmental quality and the economy in a continuous-time dynamic growth model featuring optimizing households and firms. Environmental quality is modeled as a renewable resource. Consumers can invest in government bonds or firm equity. Since investors feel partly responsible for environmental pollution when holding firm equity, they require a premium on the return to equity. We show that socially responsible investment behavior by households partially offsets the positive effects on environmental quality of public abatement policies.     

Search frictions,real wage rigidities and the optimal design of unemployment insurance

In this paper, we study the optimal unemployment benefits financing scheme when the economy is subject to labor market imperfections characterized by real wage rigidities and search frictions. The US unemployment insurance financing is such that firms are taxed proportionately to their layoffs to finance unemployment benefits. Using DSGE methodology, we investigate how policy instruments should interact with labor market imperfections. It is shown that wage rigidities in a search and matching environment cause welfare costs, especially in the absence of an incentive-based unemployment insurance. This cost is mainly due to the distorting effect of wage rigidities which generate inefficient separations. We show that the optimal unemployment benefits financing scheme – corresponding to the Ramsey policy – offsets labor market imperfections and allows implementation of the Pareto allocation. The second-best allocation brings the economy close to the Ramsey allocation. The implementation of the optimal policies clearly highlights the role of labor market institutions for short-run stabilization.     

Environmental regulation,pollution reduction and green innovation: The case of the Chinese Water Ecological Civilization City Pilot policy

This paper treats the Water Ecological Civilisation City Pilot (WECCP) policy as a quasi-natural experiment, and integrates environmental regulation, pollution reduction and green innovation into a unified analytical framework. Based on the pollution emission index and green patent data for 283 Chinese cities from 2010 to 2018, we examine the impact of WECCP policy on urban pollution emissions and green innovation by using a difference-in-differences model. The results show that the WECCP policy has significant regional pollution reduction effects, that is, the policy significantly reduces water pollution in the pilot cities, while it has a weak impact on air quality improvement. Also, we find that the WECCP policy significantly promotes the growth of the number of green patent applications in the pilot cities, indicating that the policy can significantly improve urban green innovation capacity. The mediating effect analysis shows that the WECCP policy can improve regional environmental quality by enhancing urban green innovation ability. Furthermore, the heterogeneity analysis demonstrates that the WECCP policy has more significant effects on pollution reduction and green innovation in small cities.     

On-the-job search and cyclical unemployment: Crowding out vs. vacancy effects

Incorporating on-the-job search (OTJS) into a real business cycle model has been shown to increase the cyclical volatility of unemployment. Using a particularly simple model of OTJS, we show that the increased search of employed workers during expansions induces firms to open more vacancies, but also crowds out unemployed workers in the job search, resulting in an ambiguous overall effect on unemployment volatility. We show analytically and numerically that the difference between the employer׳s share of the match surplus with an employed versus an unemployed job seeker determines the degree to which OTJS increases unemployment volatility. We use this result to re-consider some related papers of OTJS and explain the amplification of volatility they obtain. Finally, we show that a plausible calibration of the OTJS model allows us to reproduce most significant features of the US labor data.     

Pollution and informal economy

In this study, we investigate the relationship between the size of the informal economy and the level of environmental pollution/energy use. To this end, we first use different indicators of environmental pollution along with a measure of energy use intensity in a panel dataset consisting of 152 countries over the period 1999–2009 and empirically examine the relationship between pollution and the shadow economy. The estimation results show that there is an inverse-U relationship between the size of the informal economy and environmental pollution, that is, small and large sizes of the informal economy are associated with lower environmental pollution and medium levels of informality are associated with higher levels of environmental pollution. Next, we build a two sector dynamic general equilibrium model to suggest an economic mechanism for this observation. Our model identifies two channels through which informality might affect environmental pollution: The scale effect, whereby a larger (smaller) informal economy size is associated with a lower (higher) level of environmental pollution, and the deregulation effect, whereby a larger (smaller) informal economy is associated with higher (lower) pollution levels. As these two effects work in opposite directions, the changing relative strength of one with respect to the informal sector size creates the inverted-U relationship between pollution indicators and informality.     

The Costs and Benefits of Cutting Inflation

In recent speeches Treasury Ministers have coined a new slogan. They argue that inflation is not an alternative to high unemployment but a fundamental cause of it. They use this slogan to attack those who suggest that thefight against inflation should be slackened - at least briefly - in order to reduce unemployment. In this Economic e iewpoint we examine the arguments about the relation between inflation and unemployment. We suggest that although inflation may be a cause of unemployment in the long term there is an inescapable short-term choice to be made between reducing unemployment and reducing inflation. We explain why this choice arises and also discuss the longer-term effects of counter-inflationary policies. Finally we examine the record of this Government's policies so far.     

Credit constraints and the persistence of unemployment

In this paper, we argue that credit market imperfections impact not only the level of unemployment, but also its persistence. For this purpose, we first develop a theoretical model based on the equilibrium matching framework of Mortensen and Pissarides (1999) and Pissarides (2000) where we introduce credit constraints. We show these credit constraints not only increase steady-state unemployment, but also slow down the transitional dynamics. We then provide an empirical illustration based on a country panel dataset of 20 OECD countries. Our results suggest that credit market imperfections significantly increase the persistence of unemployment.     

Transboundary pollution externalities: Think globally,act locally?

We analyze the implications of transboundary pollution externalities on environmental policymaking in a spatial setting, in which pollution diffuses across the global spatial economy independently of the specific location in which it is originally generated. This framework gives rise to a simple regional optimal pollution control problem allowing us to compare the global and local solutions in which, respectively, the transboundary externality is and is not taken into account in the determination of the optimal policy by individual local policymakers. We show that it is not obvious that transboundary externalities are a source of inefficiency per se since this is strictly related to the spatial features of the initial distribution of pollution. If the initial pollution distribution is spatially homogeneous then the local and global solutions will coincide and thus no efficiency loss will arise from transboundary externalities, but if it is spatially heterogeneous the local solution will be suboptimal and thus a global approach to environmental problems will be needed to achieve efficiency. From a normative perspective, in this latter (and most realistic) case we also quantify the amount of policy intervention needed at local level in order to achieve the globally desirable goal of pollution eradication in the long run. Our conclusions hold true in a number of different settings, including situations in which the spatial domain is either bounded or unbounded, and situations in which macroeconomic–environmental feedback effects are taken into account.     

Optimal pollution control with distributed delays

We present a model of optimal stock pollution control with general distributed delays in the stock accumulation dynamics. Using generic functional forms and a distribution structure covering a wide range of distributions, we solve analytically the complex dynamic system that arises from the introduction of these distributed delays. From a theoretical standpoint, our contribution extends the dynamic optimization literature that focused on single discrete delays and develops an original method to address control problems written as mixed type functional differential equations with general kernels. Our results show the qualitative impact of acknowledging these distributed delays on the optimal pollution paths dynamics. We study analytically the properties of the dynamics and we identify the conditions for the occurrence of limit cycles. This theoretical work contributes to the design of efficient environmental policies in the presence of complex delays.     

Modeling the number of unemployed in South Sumatra Province using the exponential smoothing methods

The number of open unemployment in South Sumatra Province from year to year is found to be unstable. It can cause serious developmental problems. One solution to this problem is to build an early warning system by predicting the number of open unemployment in the future so that the Regional Government can establish relative policies to anticipate the negative impacts it will have on the environment, economy, social and politics. Therefore, this study discusses the best model to predict the number of unemployed in South Sumatra Province. The methods used to identify the best model are Single Exponential Smoothing (SES), Brown’s Exponential Smoothing (BES), and Holt’s Exponential Smoothing (HES). The Exponential Smoothing methods are compared to obtain forecasting results with a minimal error rate. Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) metrics are used to measure the performance of the forecasting model. Empirical results show that the SES model with the smoothing parameter value?=?0.7 is the best significant model in predicting the number of open unemployment in South Sumatra Province with a MAPE value of 6.24% and an RMSE value of 23.058. Thus, this SES model can be a reference for the Government to predict the number of open unemployment in South Sumatra Province so that the Regional Government can anticipate the negative impacts it can cause.

     

Youth unemployment and terrorism in the MENAP (Middle East,North Africa,Afghanistan, and Pakistan) region

This paper builds on existing research investigating the root causes of terrorism by considering youth unemployment as a measure of economic deprivation. In particular, the study focuses on terrorism in Middle Eastern and North African (MENAP) countries and features terrorism incident count data for the period 1998–2012 using negative binomial regression models. In our exogenous model, we find that while youth unemployment tends to increase domestic terrorism, it does not have any significant effect on transnational terrorism. Given concerns about endogeneity of youth unemployment in these models, we use two kinds of corrections-instrumental variables and lagged variables. We control for endogeneity by using military expenditure, under-five mortality rate and foreign direct investment as instruments. We are not able to reject the null hypothesis that youth unemployment is exogenous. Using lagged variables, we find a similar result as noted in the exogenous specifications with regard to the effect of youth unemployment on domestic and transnational terrorism. We also find evidence that domestic terrorism tends to have a positive relationship with press freedom, religious and linguistic fractionalization, and area of the country. Transnational terrorism has a positive association with the quality of democracy and a negative association with political stability and regulatory quality. The amount of natural resources tends to be negatively associated with domestic terrorism and positively associated with transnational terrorism.     

Nonlinearities and Fractional Integration in the US Unemployment Rate*

This paper proposes a model of the US unemployment rate which accounts for both its asymmetry and its long memory. Our approach introduces fractional integration and nonlinearities simultaneously into the same framework, using a Lagrange multiplier procedure with a standard null‐limit distribution. The empirical results suggest that the US unemployment rate can be specified in terms of a fractionally integrated process, which interacts with some nonlinear functions of labour‐demand variables such as real oil prices and real interest rates. We also find evidence of a long‐memory component. Our results are consistent with a hysteresis model with path dependency rather than a non‐accelerating inflation rate of unemployment (NAIRU) model with an underlying unemployment equilibrium rate, thereby giving support to more activist stabilization policies. However, any suitable model should also include business cycle asymmetries, with implications for both forecasting and policy‐making.     

Non-cooperative pollution control in an inter-jurisdictional setting

This paper examines various circumstances under which decentralized pollution policies can be efficient both in federal settings and in multi-region settings with labor mobility. We consider a model in which pollution control policies are set by regional governments non-cooperatively and pollution damages are borne by the residents of all regions. We characterize the efficiency of pollution policies, and of population allocation among regions, in a variety of scenarios, including when pollution policies are enacted before interregional transfers are determined by the federal government and before migration occurs; when migration decisions are taken before policy decisions; in the absence of a central government if regional governments can make voluntary interregional transfers; when decisions over pollution control policies are followed by voluntary contributions by regions to a national public good; when regions can commit to matching the abatement efforts of each other; and when regions can commit to specific levels of abatement contingent on the emissions of other regions not exceeding some maximum level.     

An integrated replenishment-recruitment policy in a sustainable retailing system for deteriorating products

Currently, retail facilities play a significant role both economically and socially for their contributions to job creation and to reducing unemployment. In this paper, economic, environmental, and social issues, including unemployment, job creation for the local workforce within their hometown, the immigration of an unemployed workforce, and the naturalization of non-natives are addressed for a retailer. We explore the class of deteriorating products from the viewpoint of its economic and environmental features. Then, a linear multi-objective mathematical model is developed to determine an integrated replenishment and recruitment policy for the retailer in the direction of sustainability. Using data from the flower industry, a numerical analysis is presented. The results indicate that if necessary facilities and infrastructures are provided to permanently settle qualified immigrants, both social and economic indicators will be improved. We also determine that by concentrating on strategies such as job creation for natives through retail facilities with no increase in production capacity and by applying careful policies for immigration and naturalization, social welfare can be improved.
