Endogenous information revelation in a competitive credit market and credit crunch

In this paper, we propose a new mechanism able to explain the occurrence of credit crunches. Considering a credit market with an asymmetry of information between borrowers and lenders, we assume that borrowers have to pay a cost to reveal information on the quality of their project. They decide to be transparent if it is necessary for getting a loan or for paying a lower interest rate. Two types of competitive equilibria may exist: an opaque equilibrium in which all projects receive funding without revealing information; a transparent one in which only the best projects reveal information and receive funding. It is also possible to get multiple equilibria. Incorporating this microeconomic mechanism in an OLG model, the economy may experience fluctuations due to the change of regime, and indeterminacy may occur.     

Financial crises and economic growth

This paper constructs a simple yet robust model of financial crises and economic growth where financial markets affect real economic activity. Financial markets increase real output by facilitating investment through the borrowing/lending of capital. However, the borrowing of capital is risky due to randomness in the firms’ production. Financial crises occur when output and liquid capital are insufficient to meet required loan payments and systemic defaults occur. In this model, a financial crisis caused by systemic defaults can shift the economy from an equilibrium with positive borrowing/lending to an equilibrium with no borrowing/lending. In this no-lending equilibrium, neither traditional fiscal or monetary policy tools are effective in increasing output. Fiscal and monetary policy can only increase the likelihood of the equilibrium evolving to a borrowing/lending equilibrium.     

Local Economic Structure and Growth

Abstract

This paper tests how the local economic structure—measured by local sector specialization, competition and diversity—affects growth of manufacturing sectors. Most of the empirical literature assumes that in the long run more productive regions will attract more workers and use employment growth as a measure of local productivity growth. However, this approach is based on strong assumptions, such as those of national labour markets and homogeneous labour. This paper shows that if we relax these assumptions, regional adjusted wage growth is a better measure of productivity growth than employment growth. This measure is used in order to study regional growth in Portuguese regions between 1985 and 1994. Evidence is found of MAR externalities in some sectors and no evidence of Jacobs or Porter externalities in most of the sectors. These results are at odds with the findings for employment-based regressions, which show that regional concentration and the region's size have a negative effect in most of the sectors. It is also shown that simply using regional wage growth would overstate the effect of regional concentration and competition on long-run growth.     

Abatement R&D,market imperfections,and environmental policy in an endogenous growth model

We develop an endogenous growth model featuring environmental externalities, abatement R&D, and market imperfections. We compare the economic performances under three distinct regimes that encompass public abatement, private abatement without tax recycling, and private abatement with tax recycling. It is found that the benefit arising from private abatement will be larger if the degree of the firms’ monopoly power is greater. With a reasonably high degree of monopoly power, a mixed abatement policy by which the government recycles environmental tax revenues to subsidize the private abatement R&D is a plausible way of reaching the highest growth rate and welfare.     

Credit market segmentation,essentiality of commodities,and supermodularity

We consider incomplete market economies where agents are subject to price-dependent trading constraints compatible with credit market segmentation. Equilibrium existence is guaranteed when either commodities are essential, i.e, indifference curves through individuals’ endowments do not intersect the boundary of the consumption set, or utility functions are concave and supermodular. The smoothness of mappings representing preferences, financial promises, or trading constraints is not required. Hence, we may include in our framework economies where ambiguity is allowed and agents maximize the minimum expected utility over a set of priors, or where markets include non-recourse collateralized loans.     

房地产市场的非区域性特征及其现实衍生意义

传统经济理论中,由土地区位的不可移动性引申出房地产市场是区域性市场的理论存在着逻辑上的偏差.事实上,决定某一房地产市场是否为区域性市场的判断标准在于房地产市场中的供求力量是否局限于区域之内.从这个意义上讲,房地产市场本质上并非是一个区域性市场,并且这一现象在全球化背景下表现得尤其明显.正确地认识这一假定条件对于我们思考当今中国房地产市场中的许多问题有着重要的现实衍生意义.     

The short and long-run impact of globalization if firms differ in factor input ratios

Empirical evidence has shown that exporters are more capital intensive than non-exporters. Based on this evidence, I construct a two-factor general equilibrium model with firm heterogeneity in factor intensities, monopolistic competition, scale economies and international trade. This setting can explain several empirical regularities on international trade, factor market competition, factor relocations and factor returns: (i) exporters are more capital intensive than non-exporters, regardless of a country's relative factor endowments; (ii) finite supply of capital limits a country's export activities; (iii) trade liberalization increases the relative return to capital; (iv) new profit opportunities in export markets change the distribution of firms towards the more capital intensive ones. Finally, I extend the setting to endogenous capital accumulation and show that trade liberalization induces economic growth and, in the long-run, benefits all factors in real terms.     

Entrepreneurship and economic growth: Evidence from emerging and developed countries

This paper presents an extension to the economic growth model developed by Wong, Ho, and Autio (2005 Autio, E. 2005. 2005 report on high-expectation entrepreneurship, Toronto: GEM Consortium.  [Google Scholar]), to reflect differences in the economic effects of opportunity and necessity-based entrepreneurship in both emerging and developed countries. Data from 44 countries for the years 2004 and 2005, as collected by Global Entrepreneurship Monitor (GEM) research and Global Competitiveness Report (GCR) research, are used to identify predictors of GDP growth for emerging and developed nations. The GEM data are used to determine the effect of different types of entrepreneurship on GDP growth. The GCR data operationalize additional control variables suggested by three economic growth theories: new economic geography, endogenous growth theory and national systems of innovation. This contribution to the literature suggests that, in developed countries, a significant portion of economic growth rates can be attributed to high-expectation entrepreneurs exploiting national investments in knowledge creation and regulatory freedom. However, in emerging countries this effect is absent. It is hypothesized that a threshold exists for entrepreneurs to gain access to the formal economy, below which entrepreneurial contributions act through informal mechanisms.     

Evolution of preferences and cross-country differences in time devoted to market work

I model the hypothesis that preferences evolve and permanent differences in individual attitudes towards work emerge between two countries characterized initially by identical preferences as a result of a period in which only one of the two countries is subject to regulations constraining labor supply, or as a by-product of different tax rates on labor income. Hence, the elimination of these regulations may not allow the economy thus deregulated to converge to the same hours of market work per person of the other economy, and the long-run differential in market work between economies subject to different tax rates is amplified.     

Feasibility and optimality of sustainable growth under materials balance

Pollution from consumption and production is an inevitable part of economic processes. We employ a materials balance approach and develop an endogenous growth theory, with recycling activity, to examine the evolution of the economic and environment systems. This paper provides feasibility and optimality conditions for sustainable economic growth with rising environmental quality. The fundamental condition of feasibility is that the flow of natural resources, which eventually returns to the environment as waste and pollution, has a negative growth rate in the long run.     

Spatial agglomeration and endogenous growth

This paper constructs a dynamic general equilibrium model with spatial interactions in which a human capital externality is the centripetal force towards agglomeration. The resource cost of transportation is, on the other hand, the main centrifugal force, preventing a city from growing unboundedly. A central feature of our analysis is the dynamic interaction between (perpetual) economic growth and (bounded) city growth. We examine the socially optimal and the decentralized growth rates as well as city sizes. In the decentralized environment, individuals under-invest, whereas cities are under-populated. We show how public policies may enable a decentralized city to attain the socially optimal allocation.     

Forecasting the Chinese stock market volatility with international market volatilities: The role of regime switching

The purpose of this paper is to investigate the role of regime switching in the prediction of the Chinese stock market volatility with international market volatilities. Our work is based on the heterogeneous autoregressive (HAR) model and we further extend this simple benchmark model by incorporating an individual volatility measure from 27 international stock markets. The in-sample estimation results show that the transition probabilities are significant and the high volatility regime exhibits substantially higher volatility level than the low volatility regime. The out-of-sample forecasting results based on the Diebold-Mariano (DM) test suggest that the regime switching models consistently outperform their original counterparts with respect to not only the HAR and its extended models but also the five used combination approaches. In addition to point accuracy, the regime switching models also exhibit substantially higher directional accuracy. Furthermore, compared to time-varying parameter, Markov regime switching is found to be a more efficient way to process the volatility information in the changing world. Our results are also robust to alternative evaluation methods, various loss functions, alternative volatility estimators, various sample periods, and various settings of Markov regime switching. Finally, we provide an extension of forecasting aggregate market volatility on monthly frequency and observe mixed results.     

Socio-political instability and growth dynamics

We develop an overlapping generations (OLG) monetary endogenous growth model characterized by socio-political instability, with the latter being specified as a fraction of output lost due to strikes, riots and protests. We show that growth dynamics arise in this model when socio-political instability is a function of inflation. In particular, two distinct growth dynamics emerge, one convergent and the other divergent contingent on the strength of the response of socio-political instability to inflation. Since our theoretical results hinge on socio-political instability being a function of inflation, we test the prediction that inflation affects socio-political instability positively by using a panel of 156 countries for the 1980–2012 period, and allowing for country and time fixed effects. The results indicate that inflation relates positively with socio-political instability. Policy makers should be cognisant that it is crucial to maintain long-run price stability, as failure to do so may result in high inflation emanating from excessive money supply growth, leading to high (er) socio-political instability, and ultimately, the economy being on a divergent balanced growth path.     

金融发展、FDI技术溢出与中国经济增长——基于省际面板数据的实证分析

基于1990年-2008年中国省际面板数据,就金融发展水平决定的FDI溢出效应对中国经济增长影响的实证研究表明,样本期内FDI通过其资本积累效应,对中国经济增长产生了显著的促进作用,且这一作用有随时间而强化的趋势;金融发展具有放大FDI技术溢出效应的作用,并由此对中国经济增长产生正面影响,但目前来看这一影响还比较小;"金融抑制"现象依然存在并对中国经济增长产生了不利影响,但在经历了多年的金融体制改革之后,"金融抑制"现象已有所减轻,其对经济增长的负面影响趋于减弱。     

Financial information and macroeconomic forecasts

We study the forecasting power of financial variables for macroeconomic variables in 62 countries between 1980 and 2013. We find that financial variables such as credit growth, stock prices, and house prices have considerable predictive power for macroeconomic variables at the one- to four-quarter horizons. A forecasting model that includes financial variables outperforms the World Economic Outlook (WEO) forecasts in up to 85% of our sample countries at the four-quarter horizon. We also find that cross-country panel models produce more accurate out-of-sample forecasts than individual country models.     

Financial Markets, Development and Economic Growth: Tales of Informational Asymmetries

Abstract.  The development of financial systems is very often characterised by the development of innovative financial contracts which allow a more efficient allocation of resources and a higher level of capital productivity and economic growth. By exploiting the microeconomic theory of the optimal financial contract under asymmetric information, economists have recently managed to shed new light on the well studied issue of the relationship between financial market development and economic growth. This paper reviews the most recent progress of this literature which shows that the amount of information asymmetry in the credit market and the degree of heterogeneity between borrowers (typically firms) and lenders (typically workers or savers) determine the nature of the financial system. Differences in endowments and in the level of information distribution can give rise to very different financial contracts which affect, and in turn are affected, by capital accumulation and growth.     

On the closed-form solution of an endogenous growth model with anticipated consumption

This paper derives a closed-form solution of the AK endogenous growth model with logarithmic preferences and anticipated future consumption which enters additively into effective consumption. We get an explicit representation of the time paths of the economic variables in level by resorting to Gaussian Hypergeometric functions. We compare the model with anticipated future consumption to the model with habit formation. The maximum utility attainable in the model with anticipation is shown to be higher than the one attainable in the model with habits. Using the derived explicit expressions, we perform some comparative-dynamics and -statics analyses with respect to relevant parameters. Numerical simulations complement the theoretical results. Thus, this work provides further support to the usefulness of especial functions in the study of economic dynamics.     

Information technologies, embodiment and growth

This paper studies the conditions under which an IT revolution may occur and have permanent effects on long-term growth. To this end, we construct a multi-sectoral growth model with endogenous embodied technical progress. The R&D sector expands the range of softwares. The capital sector produces efficient capital combining hardware with available softwares. Technological progress is therefore embodied: New softwares can only be run on the most recent generations of hardware. The new softwares are copyrighted during a fixed period of time. First, we analytically characterize the balanced growth paths of the model. Then we focus on the dynamic response of the economy to technological shocks. Substitution effects favorable to the IT sectors are shown to arise when positive supply shocks affect the production of efficient capital and/or the creation of new softwares. Positive shocks specific to the capital sector are unable to produce effects on long-term growth, in contrast to the shocks specific to the R&D sector.     

International spillovers of (un)conventional monetary policy: The effect of the ECB and the US Fed on non-euro EU countries

We estimate a global vector autoregression model to examine the effects of euro area and US monetary policy stances, together with the effect of euro area consumer prices, on economic activity and prices in non-euro EU countries using monthly data from 2001-2016. Along with some standard macroeconomic variables, our model contains measures of the shadow monetary policy rate to address the zero lower bound and the implementation of unconventional monetary policy by the European Central Bank and the US Federal Reserve. We find that these monetary shocks have the expected qualitative effects but their magnitude differs across countries, with southeastern EU economies being less affected than their peers in Central Europe. Euro area monetary shocks have a greater effect than those that emanate from the US. We also find certain evidence that the effects of unconventional monetary policy measures are weaker than those of conventional measures. The spillovers of euro area price shocks to non-euro EU countries are limited, suggesting that the law of one price materializes slowly.     

Equity market and money supply spillovers and economic growth in BRICS economies: A global vector autoregressive approach

Previous studies report that private credit as a proxy of financial development contributes to economic growth in BRICS economies. This paper employs three additional measures of financial development, namely equity market, money supply and market capitalization, and further investigates cross-country evidence on the impact of equity market and money supply spillovers on economic growth in BRICS economies. Utilizing a Global Vector Autoregressive (GVAR) framework and quarterly data from 1989Q1 and to 2012Q4 from BRICS economies, we find that equity market and money supply variables do not predict the contributions of financial development in each BRICS member in boosting economic growth in the other member countries. However, market capitalization significantly influences economic growth. These results suggest that, besides private credit, market capitalization is another key channel of promoting growth in individual economies and the region. Policy implications of the findings are discussed.
