城市集聚、金融外部性与地区工资差距的关系研究——以我国长三角城市圈为例

本文在KFV(Krugman-Fujita-Venables)理论模型的基础上,理清金融外部性对城市工资的影响机制,对城市间的工资差距进行解释,并采用我国长三角地级及以上城市2000-2010年的面板数据,对城市集聚对城市工资的影响进行实证分析。研究结果表明:在城市集聚过程中,金融外部性对城市平均工资水平影响显著,是影响城市工资差距的重要因素。同时,城市工资差距与城市人力资本、出口贸易、固定资产投资及第三产业比重等因素有关。此外,研究还显示我国目前的城市化和城市集聚度不足,在未来城市化推进过程中,城市间差距或将成为继城乡差距后的又一个突出问题,这一点应引起警觉。     

Impact of Trade on Canada's Employment,Skill and Wage Structure

Using newly constructed data for 88 Canadian industries (including primary, manufacturing and services), for 15 years (1992–2007), we analyse the impact of trade and technological change on labour demand, skill structure, wage premiums and welfare in Canada. Results show that export growth has no impact, whereas import growth reduces employment growth. But contrary to popular belief, Canada's job loss due to imports has been very small, only about 6,000 persons annually. China's negative impacts are more pronounced in industries where the share of information and communication technology (ICT) capital is rising fast and among low R&D intensive industries. In terms of skill change, ICT use and real exchange rate appreciation are biased towards high skill workers. Imports from the United States and China are skill‐neutral, whereas imports from Mexico are skill‐upgrading. Overall, neither export nor import growth has an impact on the wage rate. However, had there been no imports from China, the annual wage growth rate of high skill manufacturing workers would have been 0.6 per cent higher. Between 1992 and 2007, there was an annual net gain from the rise in imports at about 0.4 per cent of GDP, in addition to the gains obtained from 1992 import levels vis‐à‐vis autarky.     

Wage Hikes as Supply and Demand Shock

Wage hikes affect production costs and hence are usually analysed as supply shocks. There is a long‐standing debate, however, about demand effects of wage variations. In this paper, we bring together these two arguments in a Kaldorian model with group‐specific saving rates and a production technology that allows for redistribution between workers and entrepreneurs following a wage hike. We thereby pinpoint the conditions under which (a) wage variations affect aggregate demand and (b) the positive demand effects of wage hikes may even overcompensate the negative supply effects on aggregate employment (‘purchasing power argument’). We conclude by noting that, whereas demand effects are very likely to occur, the conditions under which the purchasing power argument does indeed hold are very unrealistic.     

Foreign Wage Premium,Gender and Education: Insights from Vietnam Household Surveys

This paper investigates the differential impacts of foreign ownership on wages for different types of workers (in terms of educational background and gender) in Vietnam using the Vietnam Household Living Standards Surveys of 2002 and 2004. Whereas most previous studies have compared wage levels between foreign and domestic sectors using firm‐level data (thus excluding the informal sector), one advantage of using the Living Standards Surveys in this paper is that the data allow wage comparison analyses to extend to the informal wage sector. A series of Mincerian earnings equations and worker‐specific fixed effects models are estimated. Several findings emerge. First, foreign firms pay higher wages relative to their domestic counterparts after controlling for workers' personal characteristics. Second, the higher the individual workers' levels of education, the larger on average are the wage premiums for those who work for foreign firms. Third, longer hours of work in foreign firm jobs relative to working in the informal wage sector are an important component of the wage premium. Finally, unskilled women experience a larger foreign wage premium than unskilled men, reflecting the low earning opportunities for women and a higher gender gap in the informal wage sector.     

The Forms and Limits of Insurance Solidarity

What makes insurance special among risk technologies is the particular way in which it links solidarity and technical rationality. On one hand, within insurance practices ‘risk’ is always defined in technical terms. It is related to monetary measurement of value and to statistical probability calculated for a limited population. On the other hand, and at the same time, insurance has an inherent connection to solidarity. When taking out an insurance, one participates in the risk pool within which each member is reciprocally responsible for others’ risks. The combination of technical controllability and solidarity has made insurance a successful tool for governing welfare societies during the twentieth century. From the point of view of business ethics, it is interesting that, as we argue in this article, the connection between insurance and solidarity is not limited to social welfare assemblages, but is evident in relation to private insurance as well. At the same time, however, it is important to understand that insurance does not advance all forms of solidarity. Hence, this theoretical article analyzes the specific conceptions of solidarity that the different forms of insurance practice produce. Particular emphasis is put on the distinction between ‘chance solidarity’ and ‘subsidizing solidarity’. The main questions of the article are: What kinds of conceptions of solidarity are built in the insurance technology? And how are the limits of solidarity defined and justified in different forms of insurance?

     

Welfare to Well‐Being Framework for Research,Education, and Outreach

The proposed framework is intended to serve as a model for understanding the comprehensiveness of welfare assistance policies that contribute to the economic well‐being of individuals and families. The framework uses a systems approach to move thinking from a narrow focus on welfare assistance as welfare for the few to well‐being of the many. Such an approach provides a new way to understand policies and language related to welfare reform.     

Self-Employment and Job Satisfaction: Investigating the Role of Self-Efficacy, Depression, and Seniority

Are self‐employed workers more satisfied with their jobs compared to wage and salary workers? Using The National Survey of Families and Households: Wave I, 1987–1988, and Wave II 1992–1994 several expectations are evaluated in this article. First, self‐employed persons should enjoy higher job satisfaction than others. Second, a portion of the association between job satisfaction and self‐employment should be explained by higher levels of self‐efficacy and by lower levels of depression among the self‐employed compared to others. Third, self‐employment veterans are a select group and should be different systematically from self‐employment newcomers with respect to reported job satisfaction. Findings offer support for the first and second arguments above but not the third. Post‐hoc analysis suggests that among the newly self‐employed, the association between job satisfaction and self‐employment depends on both the quantity and quality of time invested in the business. Implications of these findings and directions for further research are discussed.     

Mind the Gender Wage Gap – the Impact of Trade and Competition on Sectoral Wage Differences

This paper examines differences between women’s and men’s wages in 18 selected OECD countries in the period 1970 to 2005. The study is based on 12 manufacturing sector‐ and skill‐specific sets of panel data on the gender wage gap. We apply a system generalised method of moments (GMM) estimator to the extended version of the conditional gender wage gap convergence equation, controlling for sector concentration and industry‐specific measures of openness using a difference‐in‐difference approach: trade‐affected concentrated sectors versus trade‐affected competitive sectors. The results indicate that: (i) an increase in sector concentration is associated with wage gap growth; (ii) both import and export penetration are associated with a reduction of the high‐skill gender wage gap growth in concentrated industries; (iii) there is evidence of a widening impact of trade on the medium and low‐skill occupational gender wage gap growth in less competitive industries; (iv) institutional regulations of the labour market have an impact on the development of the gender wage gap: for highly‐skilled labour an increase in labour market regulation raises the growth of the gender wage gap, while for medium‐ and low‐skilled workers, it lowers it.     

Outsourcing, unemployment and welfare policy

The paper investigates the consequences of outsourcing of labor intensive activities to low-wage economies. This trend challenges the two basic functions of the welfare state, redistribution and social insurance when private unemployment insurance markets are missing. The main results are: (i) outsourcing raises unemployment and labor income risk of unskilled workers; (ii) it increases inequality between high- and low-income groups; and (iii) the gains from outsourcing can be made Pareto improving by using a redistributive linear income tax if redistribution is initially not too large. We finally derive the welfare optimal redistribution and unemployment insurance policies.     

INCOMPLETE CONTRACTS MODELLING

Contractual incompleteness has been understood in the literature as the conditions under which contracts are insufficiently state contingent due to non‐observable and/or non‐verifiable states of the world. The term incomplete contracts has been used in different meanings: to denote both proper contractual incompleteness (in a complete contracts context) due to various types of information problems, which can be contractually solved through a suitably designed mechanism and a context (an incomplete contracting context) where ex ante states of nature that are too expensive to describe prevent a contractual mechanism being designed. We examine these significantly different interpretations in both methodological and formal terms. We argue that, as long as relationship‐specific investment conditions occur, an incomplete contracting context is an innovative paradigm to the extent that it permits analysis of issues that in a complete contract context cannot even be broached, namely the recognition of non‐contractible inefficiencies and the possibility of non‐contractual solutions to such inefficiencies.     

Reassessing the foreign ownership wage premium in Germany

This paper evaluates the effect of foreign takeover on wages of workers in German establishments, using rich linked employer–employee data from 2003 to 2014. To identify a causal effect of foreign takeover, we combine propensity-score matching with a difference-in-difference estimator. We find that a takeover by a foreign investor leads to a wage premium of 4.0 log points in the year after ownership change, which further increases to 6.3 log points 3 years after acquisition. The wage premium is largest for high-skilled workers, which is consistent with three theoretical arguments, namely rent appropriation by managers, technology protection and training on new technology. We also show that the wage premium does not pick up an exporter effect due to a platform investment of the foreign owner, that it takes about 4 years before it fully develops, that it does not vanish after foreign divestment and that the wage increase is specific to foreign acquisition instead of ownership change per se.     

Trade preferences and political equilibrium associated with trade liberalization

This paper, motivated by the so-called North–South problem in trade, analyzes ex ante trade preferences and the source of potential political conflicts regarding trade liberalization. Developing a dynamic extension of the traditional Heckscher–Ohlin model with imperfect labor mobility and tracking overall dynamic paths from the autarky to free-trade steady states, we demonstrate that in the presence of inter-sectoral migration barrier, bilateral free-trade agreements can be welcomed (opposed) by the majority of workers in a capital-abundant (labor-abundant) country, which is inconsistent with the welfare prediction by Stolper and Samuelson. This paper also proposes a numerical algorithm to solve for the entire transition path of the model under rational expectation. Our simulation experiments further reveal that preannounced and delayed implementation can facilitate a bilateral free-trade agreement by partially neutralizing short-run transitional gains and losses so as to persuade the losers to support the reform without affecting the beneficiaries’ trade preferences.     

Wage Effects of Labour Migration with International Capital Mobility

Wage effects of immigration are investigated in a setting with international capital mobility, which eliminates two‐thirds of the native wage effects of immigration. Without international capital mobility, overall gains from migration in the immigration region are only a small fraction of total losses to native workers, but with perfect international capital adjustment, overall gains are larger than total losses to native workers. Two alternative tax policies to eliminate the negative wage effects of immigration on low‐skilled native workers are evaluated.     

CENTRAL GOVERNMENT BUDGET DEFICITS AND EX ANTE REAL LONG TERM INTEREST RATES IN ITALY: AN EMPIRICAL NOTE FOR 1955-1989

This paper empirically investigates the impact of central government budget deficits upon interest rates in Italy. The period studied runs from 1955 to 1989, and annual data are used. The interest rate measure is the ex ante real rate of interest. It is found, using an instrumental variables technique to control for the endogeneity of the budget deficit, that the budget deficit raises the ex ante real interest rate in Italy.     

Agency risk control through reprisal

We study agency risk control by venture capital (VC) firms to highlight the importance of VC reprisal ability. The central thesis of this paper is that a VC firm's due diligence effort as an ex ante screening for agency risk is contingent upon its ex post reprisal ability. Applying to the context of emerging markets, we develop a testable hypothesis and empirically test it using data from Singapore market. It is found that foreign VC firms that are relatively weak in reprisal ability spend more effort in due diligence screening compared to local VC firms.     

Wage Inequality in the United Kingdom: Trade and/or Technology?

I employ two alternative intra‐industry trade Applied General Equilibrium (AGE) models to explain some stylised facts of the British economy. The model with skill‐biased technical change (i.e. exogenous skill‐biased technical change à la Solow) can explain the rise in wage inequality between skilled and unskilled workers, the decline in manufacturing and the expansion of modern services. However, the model where technical change is trade‐induced (i.e. endogenous sector‐biased technical change à la Romer) performs better, because it can also explain the exponential rise of imported intermediate capital goods and developments in the wage rate of unskilled workers.     

Union-nonunion compensation differentials across plant sizes: Evidence from CPS 1983

Previous empirical work on the relationship between plant size and union-nonunion differentials has focused either on wages (Podgursky, 1986) or benefits (Bramley, Wunnava, and Robinson, 1989; Freeman, 1981). This note extends this research by simultaneously focusing on both wages and benefits. There are several arguments that can be made in explaining union-nonunion differentials across plant sizes: (1) union threat effects, (2) efficiency wage effects, and (3) wage dispersion effects. Our study focuses on measuring the union-nonunion differential in total compensation. For this end, estimates of total compensation are obtained using Mellow's suggestion (1982) for combining hourly wage information with qualitative data on pensions and health insurance, and Ross's imputations (1989) for holidays and vacations benefits. Our results, based on the May 1983 CPS supplemented by BLS data on pensions, health insurance, holidays, and vacation benefits indicate significant union-nonunion total compensation differentials exist only for workers in establishments with less than 500 workers. These results are consistent with Podgursky's wage differential findings.     

DECONSTRUCTING THE LABOUR SUPPLY CURVE

The nature and determinants of the supply of labour are re‐examined. Standard theories of labour supply, it is argued, have neglected to consider the affects of the quality of work activities on the motivation and welfare of workers. Work has tended to be seen as a means to an end rather than an end in itself and most attention has been given to the manipulation of wage incentives in affecting labour supply, to the neglect of changes in the work environment. The original contributions of W. Stanley Jevons and Alfred Marshall, in contrast, are shown to offer a fuller account of the work decision.     

Sluggish Wage Growth and Depressed Labor Force Participation

Sluggish wage growth in the post-recession era can predominantly be attributed to nominal wage rigidity, still-high underemployment, and an elevated share of part-time workers. A factor decomposition of the labor force points to the increasingly structural nature of the decline in the labor force participation rate as baby-boomers retire. Adjusting for age demographics, the decline in the participation rate is much less pronounced than appears in the official reading. The further we are from the Great Recession, the more the decline in participation becomes structural. All else equal, this points to increased tightness in labor markets which should lead to upward wage pressure in the near future.     

A Review of Insurance and Behavioral Economics: Improving Decisions in the Most Misunderstood Industry

This book indeed goes a long way towards clearing up misconceptions about insurance both on the part of consumers and, even more importantly, insurance managers and regulators. However, in the eyes of this reviewer, the authors are too quick to jump on the bandwagon of ‘Behavorial Economics’ in their attempts to explain seeming anomalies in decisionmaking with repect to insurance. This said, the case studies included, statistics cited, and arguments proffered in this the volume make for interesting reading.
