中国非农自雇活动的转换进入分析

本文利用中国健康与营养调查的微观面板数据,分析了我国非农自雇活动转换进入的决定因素。本文把初始状态区分为工资雇佣和失业,最终状态则划分为无雇工自雇和有雇工自雇,另外,对无雇工自雇转入有雇工自雇也进行了剖析。结果显示:不管初始状态如何,代际人力资本传递在自雇进入中发挥了重要作用;年龄和性别变量只对失业转入自雇有影响;由失业转入自雇的概率比由工资雇佣转入自雇的概率高;工资雇佣转入有雇工自雇的概率与失业转入有雇工自雇的概率相差不大,但工资雇佣转入无雇工自雇的概率与失业转入无雇工自雇的概率之间存在巨大差异;高等教育在无雇工自雇转入有雇工自雇的工作岗位创造过程中起到了显著的推动作用。     

The transition from paid to self-employment in Canada: the importance of push factors

The share of self-employment in total employment has been growing in Canada throughout the 1990s. Recent research for Canada and elsewhere suggests that some workers may be ‘pushed’ into self-employment as a response to inadequate opportunities in the paid sector. Examining transitions from paid work to selfemployment using the Labour Market Activity Survey, this push hypothesis is tested using a number of indicators of the economic opportunities facing the newly selfemployed. It is found: (i) longer spells of joblessness favour self-employment, (ii) workers who collect unemployment benefits between jobs are less likely to become self-employed than are workers who did not, (iii) workers who left their previous, paid jobs involuntarily - i.e., due to layoff - were more likely to become selfemployed than those who left voluntarily, but less likely than workers who specified personal reasons for leaving, and (iv) self-employment decisions are independent of the health of the labour market as measured by the unemployment rate. These results are generally consistent with the push hypothesis but provide more ambiguous evidence than found in some other studies.     

Are false own-account workers less job satisfied than true ones?

This article compares job satisfaction of true and false own-account workers. The latter group refers to own-account workers who are employed with the same tasks by the same employer for whom they previously worked as employees. To create a valid comparable group, the former workers are defined as paid employees who independently started a new business as own-account workers. Using data drawn from the European Community Household Panel for the EU-15 and controlling for possible self-selection issues, we observe that false own-account workers, compared with true ones, have less job satisfaction in terms of type of work, number of working hours, working times, and working conditions and environment. Our results are consistent with existing policies aimed to combat false self-employment developed by many OECD countries.     

An analysis of self-employment subsidies with duration models

The determinants of continuity of subsidized self-employment activities are studied by means of duration models in Asturias (Spain). Variables related to socio-economic characteristics of the self-employed and to subsidized businesses are included in the models. Moreover, to consider the economic situation, the regional unemployment rate has been taken into account. A general survival analysis is complemented with a competing risk model that considers two types of exits from self-employment (failure versus other reasons). The significant variables that explain survival are age, industry, whether the business is the main source of family income or not and the unemployment rate.     

Self-employment,financial development,and well-being: Evidence from China,Russia, and Ukraine

This study investigates the association between financial development and entrepreneurs’ well-being in China, Ukraine, and Russia. We find that Chinese and Russian entrepreneurs have a higher level of well-being, while Ukrainian self-employed individuals have more dissatisfaction. The link between financial development and the utility of entrepreneurs varies as well. The utility differences between the self-employed and paid workers in Russia reduce with financial development and the effect is stronger for job satisfaction. However, financial development barely correlates with Ukrainian entrepreneurs’ happiness while having no correlation with life satisfaction of Chinese self-employed. Further investigation suggests that the financial development – entrepreneurial utility association works through both monetary and non-monetary channels.     

The effect of self-employed health insurance subsidies on self-employment

This paper estimates the effect of an increase in the deductibility of health insurance premiums for self-employed individuals on the probability of being self-employed. Using a panel of tax returns from 1999 to 2004, we estimate fixed effects instrumental variable regressions for the probability of being self-employed, entering into self-employment, and exiting from self-employment. Our results suggest that this policy increased the probability of being self-employed by 1.5 percentage points, and increased the probability that a taxpayer would be primarily or exclusively self-employed by 1.1 and 0.35 percentage points respectively. These effects explain about a third to a half of the total increase in self-employment by these definitions over the sample period. We also find that the probability of entering self-employment increased by 0.8 percentage points and find suggestive evidence that the probability of exit decreased by 2.8 percentage points.     

The Choice of the Working Secto in Transition: Income and non-income determinants of sector participation in Kazakhstan

This study compares the individual, household and location characteristics of private employees, the self-employed, the unemployed and the economically inactive in Kazakhstan making use of a 1996 World Bank Living Standards Measurement Survey. The purpose is to understand whether the process of transition has determined a selection of workers exiting the state sector and entering the three relatively new 'pools' of private employees, self-employed and unemployed. An 'occupational choice' model is used to explore the determinants of sector participation. It is found that income opportunities are similar between the private and self-employment sectors, that the private sector is not necessarily the workers' first choice and that non-income determinants including local economic and labour market conditions and household related factors explain better than income the choice of the working sector. Self-employment seems to be a key sector in understanding the mechanisms of sector choice and the reallocation of labour. Unemployment appears as a choice of last resort and made by truly 'rationed' individuals.     

Hierarchies and entrepreneurship

We establish a correlation between the hierarchical structure of a firm and the likelihood of business creation among its former employees, using a sample of 16 million observations of Swedish workers and a novel proxy for hierarchies based on occupation data. Conditional on firm size and many other variables, employees in firms with more layers are less likely to enter entrepreneurship, to become self-employed, and to switch to another employer. The effects of layers are much stronger for business creation than for job-switching and they are stronger for entrepreneurship than for self-employment. We discuss two potential explanations for the distinctive hierarchy effect we find. Part of the effect could be to be due to preference sorting by employees, and part due to employees in firms with fewer layers having a broader range of skills. One test showing that the probability of entrepreneurship increases with their prior rank in an organization is consistent with ability sorting and inconsistent with preference sorting.     

SELF-EMPLOYMENT WITH CHINESE CHARACTERISTICS: THE FORGOTTEN ENGINE OF RURAL CHINA'S GROWTH

This article sketches a picture of the self-employment sector in rural China and examines the nature of its emergence. Using a randomly selected, nationally representative household-level data set that contains detailed information on household self-employment activities, this article provides evidence that although the self-employed enterprises are small, they have grown fast, operate as relatively complex businesses, and perform well in a financially healthy way. These results, taken together with the pattern of the emergence of self-employed enterprises across China's regions, reveal that the expansion of self-employment is not symptomatic of a failing economy; instead it is a component of the dynamic development process that characterizes rural China during its reform period. ( JEL J23, D21, O12)     

Entrepreneurship over the business cycle

The fraction of self-employed rises in recessions because wage work is more sensitive than self-employment to the business cycle, not because of necessity entrepreneurship. Graduating during a recession reduces the probability of starting a business for the next 11 years.     

Informal self-employment and macroeconomic fluctuations

Informal self-employment is a major source of employment in developing countries. Its cyclical behavior is important to our understanding of the functioning of LDC labor markets, but turns out to be surprisingly complex. We develop a flexible model with two sectors: a formal salaried (tradable) sector that may be affected by wage rigidities, and an informal (non tradable) self-employment sector faced with liquidity constraints to entry. This labor market is then embedded in a standard small economy macro model. We show that different types of shocks interact with different institutional contexts to produce distinct patterns of comovement between key variables of the model: relative salaried/self-employed incomes, relative salaried/self-employed sector sizes and the real exchange rate. Model predictions are then tested empirically for Argentina, Brazil, Colombia and Mexico. We confirm episodes where the expansion of informal self-employment is consistent with the traditional segmentation views of informality. However, we also identify episodes where informal self-employment behaves “pro-cyclically”; here, informality is driven by relative demand or productivity shocks to the non tradable sector.     

The Relative Earnings from Self and Paid Employment: A Time-series Analysis for the UK

We investigate the determinants of variations in the reported relative earnings of self-employed and paid-employed workers in the United Kingdom, focusing in particular on the significant decline which has taken place since 1980. We find that the main factors behind this decline have been the rise in the rate of self-employment itself and a reduction in the level of capital per self-employed worker; effects which we associate with a decline in the quality of the average self-employed business. Changes in the tax rates on income and in the sectoral composition of GDP helped to reduce the scale of the decline in self-employment relative earnings to some degree.     

When is your experience valuable? Occupation-industry transitions and self-employment success

The literature on employee spinoffs has, for a long time, stressed the importance of industry-specific skills and experiences in explaining the success of new firms. We argue that employees also develop skills that are associated with their occupation within an industry, and that success as an entrepreneur, therefore, is also contingent on the relation between the entrepreneurs’ previous occupation and the industry in which they operate as self-employed. Using matched employer-employee data, we develop a measure, occupational spin-offs, that accounts for this relation. An occupational spin-off is defined as a start-up in the most common industry, given the previous occupation of the founder. We then show that entrepreneurs starting occupational spinoffs enjoy above average income from self-employment and have longer spells as business owners.     

The Gender Wage Gap in Paid- and Self-Employment in Australia

This paper presents an analysis of the gender wage gap in the highly regulated Australian labour market. It compares wage outcomes in the wage and salary sector with those for the self-employed. Comparisons with the United States are provided. The large gender pay gap in self-employment suggests that the aggregate gender wage differential will not be eliminated solely through wage determination for wage and salary earners. The greater gender wage gap in the self-employed sector may reflect liquidity constraints that are more difficult for self-employed women to overcome relative to self-employed men. The comparisons with the United States suggest that women will experience deterioration in relative earnings as the Australian labour market is deregulated.     

The optimal taxation of unskilled labor with job search and social assistance

In order to explore the optimal taxation of low-skilled labor, we extend the standard model of optimal nonlinear income taxation in the presence of quasi-linear preferences in leisure by allowing for involuntary unemployment, job search and an exogenous welfare benefit. In trading off low-skilled employment against work effort of higher skilled workers, the government balances distortions on the search margin with those on work effort. Higher welfare benefits typically reduce taxes paid by low-skilled workers and raise marginal tax rates throughout the skill distribution.     

HEALTH INSURANCE COVERAGE AND ENTREPRENEURSHIP

This article estimates the importance of health insurance coverage on the probability of self-employment. Using data from the 1993 Current Population Survey (CPS), the author focuses on the impact of having health insurance through one's spouse on the likelihood of self-employment. The best estimates suggest that a guaranteed alternative source of health insurance would increase the probability of self-employment between 2.3 and 4.4 percentage points for husbands and 1.2 and 4.6 percentage points for wives. The author's more conservative estimates suggest that universal coverage could increase the percentage of self-employed in the workforce by 2 to 3.5 percentage points.     

The role of gender and its potential channels to affect self-employment in Taiwan

This research investigates the gender differences in the self-employment sector by employing a dynamic panel model with county- and city-level data from 1998 to 2016 in Taiwan. Our study is distinct from most others in this issue in that we explore not only the inter-gender difference, but also the intra-gender differences in self-employment. Following this framework, we first find that women are on average less likely to self-employ than men, and further find that older men, married men, men living in lower income regions and women living in higher income regions are more likely to become self-employed compared to their respective reference groups. We thus argue that gender influences self-employment not only directly but also through interactions with other demographic variables. Separate evaluation of different groups based on demographics should therefore result in better targeting of policies.     

The value of doing what you like: Evidence from the self-employed in 23 countries

The self-employed are substantially more satisfied with their work than employed persons. We document this relationship for 23 countries and show that the higher job satisfaction can mainly be attributed to the more interesting jobs and to the greater autonomy that self-employed persons enjoy. ‘Doing what you like to do’ seems to provide non-pecuniary benefits from work suggesting the existence of procedural utility: interesting work and autonomy are valued beyond material outcomes as good procedural work characteristics. The results hold for western European, North American and eastern European countries, but largely also for countries with a non-western cultural background.     

Competition and the cost of health care

Previous studies of the underreporting of income for tax purposes have used private employees as the benchmark to which other groups’ compliance was measured. In this paper it is suggested that there are a number of circumstances when there will be an incentive for private employees and their employers to collude to understate employee wages and salaries for purposes of taxation. The existence of high marginal tax rates of income tax combined with high social security payroll taxes are the typical conditions that stimulate this behaviour. These conditions are present in North Cyprus. This paper examines a rich source of household consumption expenditure and income data for North Cyprus that allows one to separate out the consumption expenditures made by the self-employed, private employees and civil servants over specific periods of time. From the comparison of consumption expenditures on food by these three groups it is possible to estimate how much self-employed and the private employees understated their incomes as compared to the civil servants. It is found that in North Cyprus private employees understate their incomes by approximately the same proportion of their incomes as do the self-employed.     

Can micro-credit bring development?

We examine the long-run effects of micro-credit on development in an occupational choice model similar to Banerjee and Newman (JPE, 1993). Micro-credit is modeled as a pure improvement in the credit market that opens up self-employment options to some agents who otherwise could only work for wages or subsist. Micro-credit can either raise or lower long-run GDP, since it can lower use of both subsistence and full-scale industrial technologies. It typically lowers long-run inequality and poverty, by making subsistence payoffs less widespread. Thus, an equity-efficiency tradeoff may be involved in the promotion of micro-credit. However, in a worst case scenario, micro-credit has purely negative long-run effects. The key to micro-credit's long-run effects is found to be the “graduation rate”, defined as the rate at which the self-employed build up enough wealth to start full-scale firms. We distinguish between two avenues for graduation: “winner” graduation (of those who earn above-average returns in self-employment) and “saver” graduation (due to gradual accumulation of average returns in self-employment). Long-run development is not attainable via micro-credit if “winner” graduation is the sole avenue for graduation. In contrast, if the saving rate and self-employment returns of the average micro-borrower are jointly high enough, then micro-credit can bring an economy from stagnation to full development through “saver” graduation. Thus the lasting effects of micro-credit may partially depend on simultaneous facilitation of micro-saving. Eventual graduation of the average borrower, rather than indefinite retention, should be the goal of micro-banks if micro-credit is to be a stepping stone to broad-based development rather than at best an anti-poverty tool.
