And the winner is... An empirical evaluation of unitary and collective labour supply models

An empirical evaluation is presented of two competing flexible labour supply models. The first is a standard unitary model, while the second is based on the collective approach to household behaviour. The evaluation focuses on the testing of the model’s? theoretical implications and on their ability to identify structural information, like preferences and the intrahousehold allocation process. Models are applied to Dutch microdata from the DNB Household Survey. The unitary model cannot be rejected for male and female singles, while it is rejected for a sample of couples. The alternative collective model cannot be rejected for the same sample, allowing identification of individual preferences and an intrahousehold sharing rule that can be used as a basis for welfare economic policy evaluations.     

Labor standards, labor-management bargaining and international rivalry

Using the labor union's bargaining power as an indication of government policy on labor standards issues, we analyze the competition between a domestic (North) firm and a foreign (South) firm, and their relationship with optimal labor standards (LS). First, we show that the optimal level of LS is higher when labor unions are employment-oriented than when they are not. Second, it is higher under free trade than under the optimal tariff system if labor unions are employment-oriented. Third, ‘a race to the bottom’ of LS occurs in the case of wage-oriented unions. Fourth, the North's imposing a tariff to force the Southern government to raise its LS is effective only if the Southern union is wage-oriented. In order to raise Southern LS, both countries may need some deeper form of economic integration, if the North does not want to abandon its free trade system.     

Tax decentralization,labour productivity,and employment in OECD countries

Tax decentralization should improve the efficiency of local governments and ultimately boost output growth. However, the empirical evidence is mixed. Decomposing output growth into labour productivity and employment growth, we show that the ultimate effect of fiscal decentralization on growth depends on which factor prevails, thus rendering the direct estimation of tax decentralization on growth ambiguous. Using an instrumental variable approach, with instruments based on institutional similarities and geographic distance, the empirical analysis on a sample of 20 OECD countries shows that the positive and significant effect of tax decentralization on the employment growth rate is offset by the reduction of labour productivity growth, resulting in the absence of any statistically significant effect on output growth.     

The political economy of post-crisis international standards for resolving financial institutions

The development of post-crisis international standards for resolving financial institutions highlights an intriguing puzzle: the European Union (EU), which is often considered as a ‘great financial power’, had a marginal influence in the standard-setting process, which was led by the United States (US) and the United Kingdom (UK). Why? This paper brings together and further develops the concepts of cross-border externalities derived from the hierarchical network structure of the international financial system and domestic regulatory capacity. The US and the UK had the incentives (externalities) to promote and the domestic capacity to shape international standards. By contrast, the EU was mainly exposed to regional (intra-EU) cross-border externalities and lacked regulatory capacity on the matter. Paradoxically, international standards contributed to developing EU resolution capacity by facilitating an agreement on EU (and later on, euro area) rules.     

The working poor and the working of American labour markets

This paper examines the connection between working poor householdsand industrial restructuring in the US as a whole and threeMidwest manufacturing cities. It question the conventional laboureconomics argument that a main reason for the substantial risein low-wage jobs in the US is 'skills mismatch'. This followsfrom the basic contention that people are paid what they areworth in an unrestricted economy. However, labour market segmentationtheory poses a broader range of factors as determinants of labourmarket outcomes, including industrial structure and the bargainingpower of individuals and groups of workers relative to employers.The paper first examines the nature and extent of globalisation,i.e., the transition from manufacturing to service and retailsectors, and a major consequence, growing income inequality.Government data are used to provide measures of deindustrialisationand income inequality. Government data are used to provide measuresof deindustrialisation and income inequality. It then reportson findings from a four-year study of the working poor in SouthBend, Indiana, one of the three cities studied in the firstpart. Evidence presented in the paper supports segmentationthinking and indicates that other factors beyond individualresources influence labour market outcomes, which are outsidethe control of workers, especially the working poor.     

Economic Growth: The Case of Irreversibility of Investment with Bargaining Power of Workers

In this paper, we develop a model of endogenous growth with search frictions in the labor market. We show that the growth rate of the economy may be durably altered in a case of investment irreversibility and bargaining power of workers. Labor market conditions mitigate this rent-seeking effect of workers.     

The role of the wage-productivity gap in economic activity

This paper argues that wages lagging behind productivity is a long-run structural phenomenon due to the interplay of wage dynamics and productivity growth. We call this interplay frictional growth, a term that can only be nullified in the utopian case of zero growth and/or no dynamics. In that vein, we challenge the prevailing view of the neutrality of the labour income share and investigate its impact on the evolution of employment. We thus estimate wage setting and labour demand equation systems – for France, Germany, Italy, Japan, Spain, the UK, and the US over the 1960–2008 period – and find that the labour share is negatively associated with employment even when the conventional assumption of a unitary long-run elasticity of wages with respect to productivity holds. Acknowledging the presence of the wage-productivity gap in both the short and long run, this work stands as the building block for assessing the effect of the falling labour share on economic activity. As recent work has shown that the widening wage gap is also an important factor prompting inequality, it can be argued that by supporting employment the falling labour share ‘sweetens’ the impact of rising income inequality, and, as such, deserves the attention of policy makers.     

Testing economic models of volunteer labour supply: some empirical evidence for the German Red Cross

We use a new data set collected by means of a questionnaire study of volunteers of the German Red Cross to test predictions of three competing economic models of volunteer labour supply: the public-goods model, the private-consumption model and the human-capital model. The three competing economic models make different predictions regarding the response of a volunteer’s labour supply to a change in the perceived labour supply of other volunteers. Our empirical results lend support to the public-goods model.     

A comparison of aggregation methods for measures of economic freedom

Empiricists have used various editions of an economic freedom index (EFI) initially developed by Gwartney et al. (1996) [Gwartney, J., Lawson, R., Block, W., 1996. Economic Freedom of the World: 1975–1995. Fraser Institute, Vancouver.] to examine the relationship between economic freedom and other socio-economic variables, such as growth or investment. The EFI quantifies the level of particular institutional characteristics thought to promote economic freedom and aggregates them into a single index value. The aggregation procedures utilized by Gwartney and Lawson in developing their index have changed over time and other scholars have promoted alternative methods. We examine several index aggregation procedures and show that each design may have potential methodological flaws that can greatly affect the empirical findings.

The impact of artificial intelligence on economic growth and welfare

Focusing on the self-accumulation ability and the nonrival characteristic of artificial intelligence (AI), this paper develops a three-sector endogenous growth model and investigates the impact of the development of AI along the transitional dynamics path and the balanced growth path. The development of AI can increase economic growth along the transitional dynamics path, and can increase household short-run utility if an increase in the accumulation of AI is due to the rising productivity in the goods or AI sector, but can be detrimental to household short-run utility if an increase in the accumulation of AI is because firms use more AI to replace human labor. In addition, the development of AI is not necessarily beneficial to household welfare in the long run. The main results are unaffected when considering the case where AI can improve the accumulation of human capital, the traditional research and development model, and different kinds of physical capital.     

A cost-benefit analysis for the economic growth in China

Currently, traditional development issues such as income inequality, depletion of natural resources, environmental pollution as well as retardation of infrastructure have occurred in China. In the future, more pressures would be imposed on China by the continuous fast development of industrialization, and with transfer of the world manufacture center to China. Sustainable development, including its economic, environmental and social elements, is a key goal of decisionmakers. This paper develops a methodology on cost benefit analysis of economic growth at macroscopic level to identify issues of China's sustainability. In order to address some important issues on how to make policies to improve the quality of economic growth, the CBA framework developed in this study analyses economic-ecological-social interaction, building three accounts that reflect three dimensions of sustainable development that includes 26 sub-models in all, and finally is integrated into an index as Net Progress Proceeds (NPP). The estimation methods of these submodels, such as cost of environmental pollution, depletion of natural resources and defensive expenditures are described in detail. Based on the framework and methods, this paper examines the costs and benefits of economic growth in three aspects of economy, ecology and society. The results illustrate that NPR of China's economic growth had been negative for a long time and has just became positive since year 2000 but was quite low. Even the best was only 1.6% in 2002 (the worst was − 24.2% in 1982). Based on the comparison between three accounts, we can draw a conclusion that ecological cost is the dominant factor that affects China's NPR. The empirical results show that if no other innovative measures or policies are taken in the future the costs of growth would outweigh its benefits, resulting in un-sustainability. Basically, the long-term economic growth would be unsustainable due to increasing environmental damage and depletion of natural resources. There are a few limitations that we consider need to be improved in our CBA framework and method, nevertheless they have many options that can be explored by policy makers, to make the development path more sustainable.

The labour market and the distribution of earnings: an empirical analysis for Italy

Using four waves of data from the Participation Labour Unemployment Survey, a database of information on the Italian labour market supply, we address the question of earnings dispersion by applying a ‘nested’ decomposition procedure of the Theil inequality measure, which combines into a unified framework the standard decompositions by population subgroups and income sources. The empirical evidence obtained points to the key role played by the self-employees in shaping labour income inequality, especially at the upper extreme of the earnings distribution, and the emergence of non-standard forms of employment as an important feature of the contemporary workplace.     

The ghost of financing gap: testing the growth model used in the international financial institutions

The Harrod–Domar growth model supposedly died long ago. Still today, economists in the international financial institutions (IFIs) apply the Harrod–Domar model to calculate short-run investment requirements for a target growth rate. They then calculate a “financing gap” between the required investment and available resources and often fill the “financing gap” with foreign aid. The financing gap model has two simple predictions: (1) aid will go into investment one for one, and (2) there will be a fixed linear relationship between growth and investment in the short run. The data soundly reject these two predictions of the financing gap model.     

The allocation of volatile aid and economic growth: Theory and evidence

We analyse, both theoretically and empirically, the growth effects associated with two components of volatile foreign financial assistance: ‘directly productive’ (or ‘tied’) aid and ‘pure’ aid. We find that scenarios in which aid can hurt the recipient's growth rate emerge only in cases where foreign aid is volatile. As a result, we conclude that it is only in conjunction with the presence of aid variability that aid allocation determines whether foreign aid hurts or promotes long-run growth.     

The growth-maximizing level of regulation: Evidence from a panel of international data

Existing evidence suggests that regulation diminishes economic growth. In theory, however, regulation may be either growth-enhancing or diminishing. We therefore empirically revisit the relation between regulation and growth, allowing for both positive and negative effects. In an unbalanced panel of 132 countries over eight time periods, we find evidence of a hump-shape relation between regulation and growth. The estimates imply that for more than 95% of the sample the total effect of regulation on growth is positive. The estimates also imply that about 60% of the sample observations are associated with over-regulation, relative to the growth-maximizing level. Similar findings apply to the (majority) subsample of non-OECD nations in the dataset. However, for the (minority) subsample of OECD nations, both the total and marginal effects of regulation on growth are negative.     

The effects of local govemment investment on economic growth and employment： evidence from transitional China

Based on the panel data of 28 provinces in the year of 1987-2001, this paper examines the effects of the local government investment on economic growth and employment. The empirical result shows that the local government investment plays a significant positive role in economic growth and employment. However, while the proportion of local government investment to GDP had a remarkable rise after 1998, the elasticity of local government investment on economic growth declined, which shows that there is a big room for raising the efficiency of local government investment. Moreover. the empirieal examination shows that although local government investment had positive effect on employment, the elasticity had a decrease after 1994 when the tax-sharing system reform was put into practice. This shows that the positive role of local government investment on employment is also limited This paper argues that the role of local governments as investors must be weakened, and local governments of different levels should lessen direct economic intervention and concentrate on public regulation.
