The economic costs of US stock mispricing

The USAGE model for the United States is used to quantify economic costs due to stock mispricing, made operational by shocking Tobin's q. The simulations quantify a potentially large impact even in the most favorable environment, where export demand holds up, and, the dollar is pro-cyclical. A two-year investment boom in two sectors increases consumption by a Net Present Value (NPV) amount of nearly one per cent, due to a positive investment externality onto the US terms of trade. If the investment is wasted, however, the consumption loss is nearly one-half of a per cent. A 5-year ‘capital strike’ across the whole economy subsequent to the boom - mimicking financial distress from a burst bubble - shaves around 10 per cent off consumption. Given these significant costs associated with “boom” and “bust” equity markets, we consider some, policy options that might result in greater stability in these markets.     

A model of the inflationary process in six major O.E.C.D. economies: Empirical results and policy implications

In contrast to most recent empirical work on inflation which has concentrated on the size and stability of coefficients in the wage equation, this paper provides a reexamination of the price equation. Evidence is presented on the structural determinants of inflation in six large industrial nations. It is demonstrated that price equations which include capital costs and excess demand among the regressors perform exceedingly well according to the usual statistical criteria. The results of this study indicate that the inflationary process possesses a high degree of uniformity among the larger industrial countries. This pertains not only with respect to the specific independent variables in price equations, but also with respect to the high degree of uniformity of the estimated coefficients. Additionally, the findings indicate that lower productivity growth and higher capital costs have contributed significantly to the inflationary process since 1974. Furthermore, since higher capital costs are one consequence of tighter monetary policies, the adoption of such policies in response to the two oil price shocks of the 1970s may have offset their intended deflationary effects on prices through the linkage of wage costs and aggregate demand.     

The Impact of Immigration on Skills,Innovation and Wages: Education Matters more than where People Come from

With the ensuing immigration reform in the US, the paper shows that targeted skilled immigration into the R&D sector that helps low-skilled labor is conducive for controlling inequality and raising wage. Skilled talent-led innovation could have spillover benefits for the unskilled sector while immigration into the production sector will always reduce wage, aggravating wage inequality. In essence, we infer: (i) if R&D inputs contributes only to skilled sector, wage inequality increases in general; (ii) for wage gap to decrease, R&D sector must produce inputs that goes into unskilled manufacturing sector; (iii) even with two types of specific R&D inputs entering into the skilled and unskilled sectors separately, unskilled labor is not always benefited by high skilled migrants into R&D-sector. Rather, it depends on the importance of migrants’ skill in R&D activities and intensity of inputs. Empirical verification using a VAR model in the context of the USA confirms the conjectures, and the empirical results substantiate our policy-guided hypothesis that skilled immigration facilitates innovation with favorable impact on reducing wage-gap. Inclusive immigration policy requires inter-sectoral diffusion of ideas embedded in talented immigrants targeted for innovation.     

Evaluating the effect of de facto pegs on currency crises

This paper empirically evaluates the treatment effect of de facto pegged regimes on the occurrence of currency crises. To estimate the treatment effect of pegged regimes properly, we must carefully control for the self-selection problem of regime adoption because a country's exchange rate regime choice is nonrandom. To address the self-selection problem, we thus employ a variety of matching methods. We find interesting and robust evidence that (1) pegged regimes significantly decrease the likelihood of currency crises compared with floating regimes, and (2) pegged regimes with capital account liberalization significantly lower the likelihood of currency crises compared with other regimes. From the standpoint of the macroeconomic policy trilemma, we can reasonably conclude that pegged regimes with capital account liberalization are substantially less prone to speculative attacks because they can enhance greater credibility in their currencies by maintaining strict discipline for monetary and macroeconomic policies.     

The trinity of wage setting in EMU: A policy proposal

Diverging labor cost developments are often considered to be one of the most important factors that led to large current account imbalances in the euro area (EA) in the run-up to the global financial crisis. It has also been shown that wage growth differentials have significantly lowered the co-movement of EA countries’ business cycles – the most widely used meta-criterion for optimum currency areas. Against this background, this paper develops a wage-setting benchmark that aims to keep the economy in internal equilibrium and to maintain price stability, while it also exhibits the capacity to correct for external imbalances. The proposed wage benchmark is very simple and may serve as an anchor for the macroeconomic dialogue in Economic and Monetary Union. In order to demonstrate the potentially beneficial effects of such a wage benchmark we present some simulations showing how current account balances and labor costs would have developed across EA countries if the rule had served as a benchmark already in the run up to the crisis.     

Moderate wage increases and flexible labour contracts to protect employment in Colombian manufacturing

Based on conditional and unconditional demands for labour, we exploit the variations of real minimum wage across manufacturing subsectors to present evidence that this variable affects formal employment. The long-term elasticity of labour demand to the minimum wage is around –0.7. Accordingly, increases in the minimum wage lead to job losses for unskilled labour, mainly in plants with fewer than 100; thus, small increases in the minimum wage are desirable to protect employment. Labour demand is highly cyclical: the output elasticity is about 1.7. Thus, some flexibility in labour contracts is desirable to reduce the link between employment and variation of plants’ sales. Open-ended labour contracts might allow reductions of the nominal wage rather than inducing job losses during periods of severe slumps, as has happened during the COVID-19 pandemic.     

The decomposition of regional wage differentials in Korea

This research note explains the wage differentials between the capital region and the non-capital region in Korea. It analyzes what proportions of the wage differential are due to differences in productivity-related labor characteristics and due to differences in how markets value the endowments of their workers. In a decomposition analysis, we find that approximately 26.9% of the wage differential is due to differences in productivity-related labor characteristics in the capital region. With respect to the endowments of the wage-determining characteristics, a substantial portion of the overall wage advantage of workers in the capital region can be explained by the higher average level of education. It is also found that the more detailed the occupational breakdown, the more of the wage differential that can be explained. These results suggest that the use of more detailed occupation classifications alleviates aggregation bias that may be a significant factor in coarser classification schemes.     

Betting the farm on high food prices: A consumer based approach to agriculture protection

Our question is quite simple: If agriculture protectionism is a product of economic development, why is agriculture protected at such varying degrees by otherwise similarly developed countries? Previous attempts to fit agriculture into general models of trade policy formation have relied exclusively on producer demand for protection and merely assume the associated demand for lower prices that might come from consumers. Not surprisingly, these previous studies add only minimally to this strange phenomenon. Our method turns this approach on its head by modeling the political strategy of agriculture protection on the costs incurred by the consumer. Taking both producers and consumers into account more accurately reflects the intent of extant theoretical models of protectionism. Our results show that using the consumer as the dependent variable provides more robust results on common independent variables. Recent global events show that consumer disapproval of agriculture policies should not be underestimated by political scientists or politicians.     

A POLITICAL ECONOMY OF THE SOCIAL WAGE: THE NET SOCIAL WAGE IN AUSTRALIA, 1964–65 TO 1991–92

This article attempts to place the concept and measurement of the social wage into a context of political economy. Several variations on the conventional method of measuring the social wage are proposed and applied to Commonwealth outlays for the period 1964–65 to 1991–92. It is argued that the resulting concept is better suited to an analysis of the impact of government social expenditures on capital accumulation. While the alternative ‘Net Social Wage’ concept must be a qualifiable measure of the redistributive impact of such expenditures, it is argued also that it is a more meaningful one than the conventional measure presented in most studies on this subject.     

工资上涨能提升劳动报酬份额吗?——基于要素替代弹性的解释

基于要素替代理论研究工资上涨与劳动报酬份额上升的关系,发现在不同经济状态和发展时期,提升劳动报酬份额不应单纯依赖增加工资.工资水平的上升会导致劳动相对资本要素价格提升,而生产要素相对价格的变动与劳动报酬份额的关系依赖于要素替代弹性水平.从实证角度出发,首先使用上市企业数据测算得到要素替代弹性的数值,检验了要素替代弹性对资本相对价格与劳动报酬份额关系的中介作用.在此基础上,从Hicks提出的要素替代弹性概念内涵中发掘了理论模型,结合中国实证数据分析了要素替代弹性的影响因素.研究发现,2001年至今中国要素替代弹性整体小于1且呈增长趋势,但部分行业存在要素替代弹性大于1的情形,在此状况下提高工资水平会导致劳动报酬份额下降.因此工资上涨并不一定带动劳动报酬份额提升,只有在劳动要素以技能工人为中心、产业结构以非资本密集型为核心的情况下,工资上涨才能拉动劳动报酬份额持续上升.     

Women's Wages: Cohort Differences in Returns to Education and Training Over Time*

Objective. This article examines the effects of education and work‐related training on wage‐growth trajectories for two cohorts of women as they aged from their early 20s and 30s into their early 30 s and 40 s. I test whether occupational training compensates for an earlier lack of education, thereby decreasing earnings inequality over time within cohorts. Because the broader economic context may influence the relationship between wages, education, and training, I test the assumption that the experiences of a given cohort may be generalized to others. Methods. Following NLS Young Women between 1977 and 1987 and NLSY79 Women between 1988 and 1998, growth‐curve analyses test whether returns to investments in human capital vary over time, across and within cohorts. Results. Women who did not update their skills over time experienced stagnation or declines in real wages, leading to growing wage inequality within education levels. However, women without a high school degree who engaged in on‐the‐job training experienced the greatest returns to training, thus reducing the initial education‐based wage gap. Conclusion. Education and training in adulthood can deflect the accumulation of disadvantage, but can also solidify an already uneven distribution of resources across social strata.     

Work Choices: the low productivity road to an underclass

The passage of the Work Choices Act 2005 serves to eliminate one of the last symbols of fairness in Australian society; the judicially‐determined conciliation and arbitration system and wage‐setting machinery. In this paper we examine the flawed conceptual framework, which underpins the Government's view that reducing the rights and protections of workers will produce superior labour market outcomes. We argue that the principal failure of the Work Choices Act is that it ignores the role of macroeconomic policy in directly addressing the efficiency and equity issues that have been said to motivate its provisions. The Act also ignores the different bargaining power of workers and capital and pays no attention to the serious social repercussions that will flow when labour is treated like a commodity. The imperative to minimise labour costs under Work Choices will spur a race to the bottom and the profusion of insecure, low‐paid, poor‐quality work in an economy characterised by allocative and dynamic inefficiency.     

Social protection: An obstacle to employment?

This article examines the ambivalent effect of social security on employment. First, an international comparison looks at protection from layoff by the employer, wage floors as defined in social and employment legislation, and levels of wage-related costs and their effect on employment. Simulations for western Germany are then used to analyse the effects on the labour market of lowering social security contributions. The conclusion which emerges is that the effects of social protection on employment are determined both by the way it is organized – and thus ultimately how much it costs – and by the way it is funded, i.e. who picks up the bill for social security.     

An economic analysis of nanofood labeling

The paper examines the economic effects of labeling food nanotechnology products using an analytical framework of heterogeneous consumers and imperfectly competitive suppliers. Labeling results in increased costs for nanofood producers (the cost effect of the labeling policy), reduced consumer uncertainty regarding the nature of the food product (certainty effect), and can affect consumer attitudes towards nanofoods by being perceived as a warning signal (stigma effect). In this context, nanofood labeling can change the perceived quality differences between nanofoods and their conventional and organic counterparts, with such changes being more salient when the stigma effect is large, when consumers have low awareness of food nanotechnology in the absence of labeling, and/or when competition among nanofood suppliers is more intense. Despite its empirical relevance, the impact of a labeling policy on consumer preferences (and the economic ramifications of such impact) has largely been ignored by the theoretical literature on the economics of labels. Our analysis shows that it matters. Specifically, our study shows that the market and welfare effects of labeling are case-specific and dependent on consumer awareness of, and attitudes towards food nanotechnology before and after the introduction of the policy as well as the relative magnitude of the cost, certainty and stigma effects of nanofood labeling. Our analytical findings also suggest that the effects of nanofood labels on consumer welfare are asymmetric with certain groups of consumers benefiting even when labeling has a stigma effect on nanofoods.     

The impact of a Tax-Based Incomes Policy on U.S. macroeconomic performance: An optimal control study

This study attempts to estimate the potential impact of a Tax-Based Incomes Policy (TIP) on macroeconomic performance by applying an optimal control algorithm to the Wharton Quarterly Econometric Model. A TIP is any tax incentive that would induce firms and/or workers to reduce wage increases. Our study is applicable to any version of TIP. To isolate TIP's potential impact, we compare the optimal path of the economy without TIP to the optimal path of the economy with TIP. Our conclusion is that a TIP may be able to significantly improve the path of inflation, unemployment, and real GNP simultaneously.     

The economic consequences of the welfare state

What are the economic and employment consequences of larger social insurance programmes? Are larger welfare states diverting resources from economic activity and distorting the investment decisions of firms? I examine theoretical and empirical research on the economic consequences of the welfare state. This review shows that the predictions of a negative relationship between higher levels of social protection and growth have not been borne out in the data. Both insurance programmes and other policies that increase investment in human capital or the overall productivity of workers generate important economic externalities that outweigh the potentially distortionary effects of higher taxes. Empirical studies also fail to uncover a consistent negative relationship between larger welfare states and the level of employment. The employment consequences of the welfare state are mediated by existing institutions and policies—such as the level of centralization of the wage bargaining system—which affect the redistribution of the costs of higher taxes among workers and firms. As a result, the employment consequences of larger welfare states are non-linear.     

Do political instability,financial instability and environmental degradation undermine growth? Evidence from belt and road initiative countries

This study investigates the extent to which political instability (PI), financial instability (FI), and environmental degradation undermine economic complexity (EC). EC is more predictive of future growth and development patterns and correlates with the increased ability to create and export a wide variety of sophisticated (high productivity) items. Using data from up to 56 BRI nations, I routinely obtain precise estimates of the negative effect of PI and FI on EC. Further, we examined the indirect effect of PI and FI through the channel of human capital (HC). These findings confirm the core premise that institutional stability largely influences economic complexity by encouraging creative entrepreneurship, HC accumulation, and allocating human resources to productive activities. Moreover, we examined the indirect effect of PI and FI through the channel of CO₂ emissions. These findings support the idea that countries with stable institutions can reduce pollution and protect the environment. It could increase economic complexity while reducing environmental degradation. The main findings support the creation of a pro-development institutional framework that enhance environmental sustainability and reduces poverty by increasing economic complexity.     

Parenting stress and behavior among single mothers of preschoolers: The mediating role of self‐efficacy

Abstract

This study examines the role of perceived self‐efficacy in mediating relations between mothers’ parenting behavior and variables such as maternal employment status, depressive symptoms, parenting stress, and child behavior problems. Subjects were 93 employed and 95 nonemployed, single, black mothers of a 3–5‐year‐old child who were current and former welfare recipients. Using linear structural relations modeling (LISREL), the findings support a model whereby (a) the more behavior problems the child is perceived to have, the more depressive symptoms the mother feels; (b) the more depressive symptoms the mother feels, the more likely she is to rate herself high in parenting stress; (c) the more depressive symptoms and parenting stress the mother experiences, the lower is the mother's estimate of her self‐efficacy; and (d) the lower the mother's self‐efficacy, the less competent is her parenting. The findings for employment status are similar; i.e., maternal employment predicted a trajectory leading to somewhat better parenting. In addition, child behavior problems were associated with less competent parenting both directly and indirectly through their effect on parenting stress and self‐efficacy. These results suggest that self‐efficacy has import as a mediator of the relations between maternal parenting and other psychosocial variables. There is no evidence, based on these findings, that employment in the low‐wage market is harmful either for single black mothers or their preschool children. However, job availability and an increase in the minimum wage are important policy considerations.     

Exchange rate and wage policies in Central and Eastern Europe

After the eastern enlargement of the European Union (EU) and due to increasing labor market integration, wage determination in Central and Eastern Europe (CEE) has become a key issue in European economic policy making. In addition, a controversial discussion concerning the monetary integration of CEE countries into the EMU has emerged. Both issues have earned particular academic and political interest because Eastern and Western Europe are at different stages of economic development and volatile international capital flows seem to require either a higher degree of wage or exchange rate flexibility. Based on the Scandinavian model of wage adjustment by Lindbeck (1979), we analyze the role of exchange rates in the wage determination process of the Central and Eastern European countries to identify which exchange rate strategy contributes to faster wage convergence in Europe. Panel estimations suggest that workers in countries with fixed exchange rates are likely to benefit in the long run from higher wage increases.     

Do labour market policies reduce the informal economy more effectively than enforcement and deterrence?

In 2006, Turkish policymakers introduced new measures to reduce informality and encourage formality, in which the primary means of combatting informality were stricter enforcement of existing labor market laws and deterrence through fines, without any appropriate adjustments in formal labour costs. In this paper we show that even without any change in enforcement and deterrence, in an economy growing with capital accumulation like in Turkey, informality gradually and naturally declines. Furthermore, we propose alternative labour market policy changes like reductions in minimum wage and payroll taxes to reduce informal employment share, and assess the relative effectiveness of these policy changes.
