The Effects of a Consumption Tax on Effective Demand under Stagnation

This paper investigates the effects of a consumption tax on effective demand under stagnation. The existing work shows that a consumption tax does not influence effective demand in the case of a homogeneous household under stagnation. In this paper there are two types of household. One is the richer household, whose level of total assets is relatively high. The other is the poorer household, which owns fewer total assets. In a lump‐sum transfer, when the ratio of the poorer household to the total population is large (small), imposing a consumption tax decreases (increases) effective demand.

Business cycles synchronization in East Asian economy: Evidences from time-varying coherence study

This paper analyzes the feasibility of a monetary union in East Asia focusing on business cycles synchronization. Considering the critical role of trade integration in the East Asian integration process, we study whether East Asian countries are characterized by business cycle synchronization. The related empirical literature dedicated to business cycles synchronization in East Asia does not lead to firm conclusion. In this paper, we suggest a different empirical approach allowing, contrary to the previous studies, to detect endogenously structural changes in the comovement process between outputs. We apply a new measure based on the time-varying coherence function. Such a measure not only detects comovement dynamics but it distinguishes also this dynamics between short- and long-term. We compute also cohesion statistics to test if countries tend to be more synchronized or not. The main finding of this paper is that the increase in bilateral trade inside the East Asian region significantly improves long-run business cycle synchronization. The short-run influence of bilateral trade shows mixed results. Indeed, short-run cycles remain significantly influenced both by shocks hitting each country and by economic policy responses. As a consequence, more bilateral trade and convergence in economic policy constitute two complementary processes to promote business cycle synchronization.     

Complementarity and substitutability between farm and nonfarm activities: Evidence from agricultural households in Tanzania

Increasing evidence shows that farm households in developing countries maintain a portfolio of income-generating activities. Concerns have been raised that household income diversification to include nonfarm activities will stifle farm works, and thus reduce agricultural productivity. On the contrary, some evidence of complementarity between the farm and nonfarm activities in rural areas has been found. This paper uses data from the fourth and the fifth waves of Tanzania's National Panel Surveys to examine whether there exists complementarity or substitutability between farm and nonfarm activities in rural Tanzania. The findings show that participation in off-farm work and nonfarm business activities has no clear relationship to the adoption and use of improved agricultural practices, namely, irrigation, fertilizers, pesticides, and herbicides. Participation in off-farm work and nonfarm business activities does not also seem to directly influence agricultural investments, production, and productivity nor overall household income. These results suggest that the complementary and substitution effects of nonfarm activities offset each other in Tanzania, implying that proper policies are required to unleash the potential impact of nonfarm activities on agriculture.     

The impact of electronic commerce on small and midsized spanish companies

Electronic commerce (EC) is not new for some European Union countries, but in others, such as Spain, it is only at the developmental stage. Now that Spain has joined the third phase of the economic and monetary union, Spanish companies' internationalization and the progressive change in the Spanish consumers' buying habits are determining the search for new business strategies. Starting with an analysis of the Spanish business environment, followed by an internal scanning of small and midsized Spanish companies, this paper will analyze the viability of EC as a new business strategy.     

Gender differences in the volatility of work hours and labor demand

This paper examines the role of heterogeneity in a real business cycle model, which traditionally has not fully captured the relative volatility of hours to output. Men and women have different cyclical volatilities in hours worked, which is robust to different filtering methods. This empirical regularity is used to motivate a standard RBC model augmented to allow for two different agents following Jaimovich et al. (2013). These two agents have identical utility functions, but face different elasticities of labor demand due to their different complementarities with capital. These estimated elasticities find that women are more complementary to capital. The calibrated model generates the cyclical volatility of work hours by gender and for the total hours worked that matches the U.S. data better than the traditional representative agent model. I then explore other extensions to this model including investigating the stability of the estimated labor demand elasticities and allowing for various Frisch elasticities of labor supply. This paper demonstrates that allowing for even broad levels of heterogeneity in a simple framework can increase the model’s tractability with the data. Since gender is important to explain U.S. business cycle dynamics, we need to carefully consider heterogeneity when analyzing counter-cyclical economic policy, as it may not have symmetric effects across assorted groups.

Improving Global Competitive Capability, through Customization： Model, Method and Strategies

As the environment of market competition is rapidly changing, the model of competition also changes consistently. This paper focuses on the changing process of global competition model based on the analysis of production model and its tendency of development, especially analyses the positive effect of mass customization. The paper introduces the concept of market turbulence to decide the occasion of transformation to mass customization for industries/enterprises. Several transformation roadmaps to mass customization and competitive models and strategies are established.     

Cross‐country diffusion of ideology via FDI

This paper studies how foreign direct investment (FDI) contributes to ideological convergence across countries. In particular, this report focuses on whether multinational firms transfer freedom of speech (FOS) to local workers in China. Using a large source of individual survey data, it is found that those who work in foreign‐invested enterprises (FIEs), especially non‐Hong Kong, Macao and Taiwan (non‐HMT) invested enterprises tend to prefer FOS. This is in contrast to enterprises that do not work in FIEs. Such patterns are also observed in other related human rights and cultural measures common to Western democracies, but not China's political and local culture. Using policies on FDI as exogenous instruments, and other complementary identification strategies, a causal link for such an ideological transfer is established.     

Third‐degree price discrimination in the presence of congestion externality

This paper analyzes third‐degree price discrimination of a monopoly airline in the presence of congestion externality when all markets are served. The model features the business‐passenger and leisure‐passenger markets where business passengers exhibit a higher time valuation, and a less price‐elastic demand, than leisure passengers. Our main result is the identification of the time‐valuation effect of price discrimination, which can work in the opposite direction as the well‐known output effect on welfare. This time‐valuation effect clearly explains why discriminating prices can improve welfare even when this is associated with a reduction in aggregate output.     

Informal economy, wage goods and accumulation under structural adjustment theoretical reflections based on the Tanzanian experience

Economic development in sub-Saharan Africa under structuraladjustment witnessed the upsurge of informal sector development—thedevelopment of unregulated labour-intensive activities, in partexport-oriented. This paper argues that two factors played animportant role in shaping the dynamics of informal sector development:(1) the process of the relative cheapening of wage goods asa result of their importation, partly financed through foreignaid, thereby lowering unit-labour costs in labour-intensiveproduction, and (2) the processes at work of subsidising realwages by other forms of economic security as a result of multiple,diversified and spatially extended livelihood strategies. Whilethese factors undoubtedly brought a new vitality to economicdevelopment, this paper questions the long-run sustainabilityof this new trend for two reasons. One is its dependence onforeign aid to finance imports. The other is that it does notappear to propel endogenous increases in productivity by achievinggreater synergy in intersectoral linkages between agricultureand industry.     

控股股东股权质押、控制权转移风险与广告投入

股权质押使控股股东面临控制权转移风险,其有动机进行市值管理。本文以2011-2019年中国A股上市公司为样本,考察股权质押情境下控股股东是否存在调整广告投入的行为。研究结果发现,控股股东进行股权质押后,公司广告投入水平显著提高,说明股权质押情境下控股股东会通过策略性地增加广告投入进行信息管理,而非通过削减广告投入进行向上盈余管理,证实广告具有短期股票回报效应;控制权转移风险较大时,控股股东股权质押对广告投入的正向影响更明显,说明股权质押情境下控股股东增加广告投入是出于缓解控制权转移风险的动机。进一步研究发现,在散户规模较大和产品直接与消费者接触的企业,广告更容易吸引投资者注意力,此时控股股东增加广告投入的动机更强,该行为短期内可以提振股价,但没有起到改善经营业绩的作用且加剧了股价波动。本文为资本市场和产品市场的联系提供了证据,且对相关部门加强上市公司广告费用监管具有一定的政策参考价值。     

Individuality and the economic order in Hegel's Philosophy of Right

This paper examines Hegel's perspective on the market economy, paying particular attention to how the market fits into his conception of freedom. Hegel's doctrine of freedom implies that market relations realize a distinctive form of freedom; however, due to the ontological deficiencies of this freedom, it must be subsumed under a superior freedom that is realized only within the state. The paper also explains why Hegel, although an economic liberal, does not accept the basic tenets of political liberalism, and why he does not regard economic science as a tool for public policy.     

Religion in macroeconomics: a quantitative analysis of Weber’s thesis

Max Weber in 1905 claimed that Protestantism, and more specifically Calvinism, facilitated the rise of capitalism. This paper assesses the quantitative plausibility of his hypothesis by introducing religious beliefs into a dynamic general equilibrium model of development and growth. Through counterfactual exercises, the paper investigates whether differences between Catholics and Protestants most closely identified with the Protestant Work Ethic can account for long delays in the start of Industrialization observed between various countries and regions. The main finding is that these differences may possibly explain why Northern Europe developed before Southern Europe, but they cannot explain why Europe developed before Latin America.

Many of the tenets of Calvinism have had profound social implications–in particular, that thrift, industry, and hard work are forms of moral virtue and that business success is an evidence of God’s grace. Because these views helped to create a climate favorable to commerce, Calvinism played a role in the overthrow of feudalism and the establishment of capitalism. Microsoft Encarta

Great moderation or “Will o’ the Wisp”? A time–frequency decomposition of GDP for the US and UK

In this paper the relationship between the growth of real GDP components at different cycle lengths is explored in the frequency domain using discrete wavelet analysis. This analysis is done for both the US and the UK using quarterly data, and the results reveal interesting differences between the two countries. One of the key findings is that the “great moderation” shows up only at certain frequencies, and not in all components of real GDP. A second result is that the great moderation appears to have shifted cyclical power from shorter and business cycles to long cycles, which has important implications for both policy formulation and the probability of less frequent but more severe economic crises. We use these results to explain why the incidence of the great moderation has been so ephemeral across GDP components, countries and time periods. This also explains why it has been so hard to detect periods of moderation (or otherwise) reliably in the aggregate data.

Multi-dimensional risk and the cost of business cycles

This paper analyzes the welfare costs of business cycles when workers face uninsurable idiosyncratic labor income risk. In accordance with the previous literature, this paper decomposes labor income risk into an aggregate and an idiosyncratic component, but in contrast to the previous literature, this paper allows for multiple sources of idiosyncratic labor income risk. Using the multi-dimensional approach to idiosyncratic risk, this paper provides a general characterization of the welfare cost of business cycles when preferences and the (marginal) process of individual labor income in the economy with business cycles are given. The general analysis shows that the introduction of multiple sources of idiosyncratic risk never decreases the cost of business cycles, and strictly increases it if there are cyclical fluctuations across the different sources of risk. This paper also provides a quantitative analysis based on a version of the model that is calibrated to match US labor market data. The quantitative analysis suggests that realistic variations across two particular dimensions of idiosyncratic labor income risk increase the welfare cost of business cycles by a substantial amount.     

Oil price shock and informal workers in dual labor markets

This paper examines the impact of a rise in oil prices on the wages of workers in the unorganized sector of a developing economy. The model economy is comprised of two non-traded transport sectors, formal and informal, along with other sectors. The main results that we obtain are as follows. The informal transport sector contracts when fuel price rises and lowers the real income of the informal workers. The per-unit return to land rises, and the factor readjustments even raise the output of other sectors in the economy. We also show why inclusion of non-passenger transport services does not alter the main outcomes of the model.
