Clusters And Strategy In Regional Economic Development, Edward Feser Dec 2009

Clusters And Strategy In Regional Economic Development, Edward Feser

Edward J Feser

Many economic development practitioners view cluster theory and analysis as constituting a general approach to strategy making in economic development, which may lead them to prioritize policy and planning interventions that cannot address the actual development challenges in their cities and regions. This paper discusses the distinction between strategy formation and strategic planning, where the latter is the programming of development strategies that are identified through a blend of experience, intuition, and analysis. Cluster theories and analytical tools can provide useful informational inputs into a strategy making effort and they can also be helpful for programming specific interventions (i.e ...


The Effects Of Devaluation Of The Tenge Upon The Kazakhstan Economy, John Ja Burke Aug 2009

The Effects Of Devaluation Of The Tenge Upon The Kazakhstan Economy, John Ja Burke

John JA Burke

This article examines the probable effect of the February 2009 devaluation of the Tenge on the Kazakhstan economy. Conventional wisdom holds that currency devaluation increases exports, protects domestic production, and preserves foreign exchange currency reserves. While the latter states the obvious, the causal relation between currency devaluation and increased export revenue and increased domestic production, though logically valid, requires the passage of time to measure. In the context of Kazakhstan, the question of devaluation and its effects also must be examined within the “Dutch Disease” model, as Kazakhstan is an oil dependent country. History teaches that devaluing the Tenge is ...


A Nation In Dilemma, Professor Issam A.W. Mohamed Aug 2009

A Nation In Dilemma, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

following the Global financial Crisis there were economic collapses in all the world. Sudan officials claimed that the country was immune from that epidemic. Such declaration were truly weird as it has been deeply affected from the first instant. That article presented many questions about the economic and social conditions and the eminent southern Sudan, Darfur crises.


Some Remarks On The Effects Of Active Labour Market Policies In Post-Transition, Joanna Tyrowicz, Piotr Wojcik Jul 2009

Some Remarks On The Effects Of Active Labour Market Policies In Post-Transition, Joanna Tyrowicz, Piotr Wojcik

Joanna Tyrowicz

Social cohesion is the principal goal behind active labour market policies (ALMPs), including those financed at supra-national level, like the European Social Fund. In this paper we use NUTS4 level data on the local labour market dynamics in an attempt to verify direct and indirect effects of ALMPs. We use data for 2000-2007 for Poland, while this period comprised both stark increases and reductions in the unemployment rates. Over this time also the financing of ALMPs has been increased considerably, transforming both to higher intensity of ALMPs (wider coverage) and higher extensiveness of these activities (increase in per treatment cost ...


Quantifying The Value Of Us Tariff Preferences For Developing Countries, Judith M. Dean, John Wainio Jul 2009

Quantifying The Value Of Us Tariff Preferences For Developing Countries, Judith M. Dean, John Wainio

Judith M Dean

In recent debates, trade preference erosion has been viewed by some as damaging to developing countries, and by others as insignificant, except in a few cases. However, little data have been available to back either view. The objective of this paper is to improve our measures of the size, utilization and value of all US non-reciprocal trade preference programs, in order to shed some light on this debate. Highly disaggregated data are used to quantify the margins, coverage, utilization and value of nonagricultural and agricultural tariff preferences, for all beneficiary countries in the US regional programs and in the GSP ...


The Janjaweed And The Armed Movements Of Sudan, Professor Issam A.W. Mohamed Jun 2009

The Janjaweed And The Armed Movements Of Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The emergence of the Janjaweed as an armed force working with the government to suppress rebellions in Darfur region outraged the international community. They were marked by brutality, destruction, burning, killings and mass rapes. They were also described as Arabs. However, that was not the whole picture, no one observed the living conditions of the Arabs or how were they victims also as the other inhabitants of Darfur. No one also observed that they were used by the Ingaz government to execute the dirty work and bear the consequences. The Arab tribes however, also had other thoughts as they realized ...

Assessing The Viability Of Investment In Sudan (1979-2008), Professor Issam A.W. Mohamed May 2009

Assessing The Viability Of Investment In Sudan (1979-2008), Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Most developing and underdeveloped countries beside Sudan suffer from low levels of income in addition to the low savings that are result from the lack of public savings channels. Hence, investments depend on the individuals' abilities on savings where they are major motivating vehicle for economic activity due to its direct correlation with capital accumulation process that increases the productive capacity for the national economy and help to create job opportunities and achieving economic development. Subsequently, the importance of the investment comes from the effective role that can be practiced on the national product. Currently, Sudan endures severe economic crisis ...


Rogue Counrty And Potential Cooperation: The United States And Sudan And Feasible Economic Partnership, Professor Issam A.W. Mohamed Apr 2009

Rogue Counrty And Potential Cooperation: The United States And Sudan And Feasible Economic Partnership, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The United States declared Sudan as a rogue country in 1995 due to many political considerations. It has imposed many economic and political sanctions against it since that time which represented hindrance to development and resulted in economic crises. Oil explorations started long time by Total Oil Company and resumed by Chevron that halted her activities in Sudan after the flaring of the civil war between the Northern and Southern parts of the country. That work was resumed in 1996 by Chinese companies and was crowned by success and commercial production in 1999. Although the economic situations of Sudan improved ...

Explaining Trade Flows: Traditional And New Determinants Of Trade Patterns, Julien Gourdon Mar 2009

Explaining Trade Flows: Traditional And New Determinants Of Trade Patterns, Julien Gourdon

Julien Gourdon

An empirical tradition in international trade seeks to establish whether the predictions of factor abundance theory match with the data. In this paper, we test if the "new" determinants used in the factor content version of H-O-V models (differences in productivity, in returns to scale or in consumers' preferences) help us to improve our estimation of trade patterns in commodities. The results show that conventional factors are still important in determining trade structure although new determinants need to be included to determine comparative advantage. Turning to the change across periods, differences in factor endowments have not diminished over time: we ...


欧盟经济趋同分析与我国区域政策选择, 邓翔, 路征 Feb 2009

欧盟经济趋同分析与我国区域政策选择, 邓翔, 路征

Zheng Lu (Chinese: 路征)

对欧盟人均 GDP差异的实证研究发现 , EU15 与EMU 并不存在整体上的δ趋同 ,β趋同检验显示初始人均GDP与增长率之间也仅体现出弱负相关关系。欧盟这一表现伴随着欧盟备受推崇的区域经济政策而出现 ,其艰难过程为我国区域经济一体化战略提供了参照。但是 ,应充分考虑我国区域经济一体化与欧盟国区域一体化的差异 ,制定合理的区域一体化政策。


政治资源、 经济资源与收入差距, 路征 Feb 2009

政治资源、 经济资源与收入差距, 路征

Zheng Lu (Chinese: 路征)

在制衡机制缺位的前提下,政治资源和经济资源的扭曲结合恶化了资源分配的不平等,它是居民收入差距和地区收入差距扩大的重要原因。 文章认为,解决政治资源分配不均以及由其导致的经济资源分配不均,即实现政治资源和经济资源的合理结合,对缩小收入差距有积极作用,也是进一步值得研究的重要课题。


欧盟区域差距演变的历史测度, 邓翔, 路征 Feb 2009

欧盟区域差距演变的历史测度, 邓翔, 路征

Zheng Lu (Chinese: 路征)

《罗马条约》之后,欧盟的地区差距问题一直是欧盟政策的重点。文章利用欧盟近50年的数据,采用基尼系数、变异系数和泰尔指数分别对欧盟区域差距的历史演变做了全面分析,主要结论是,EU15区域差距以1980年代初期为转折点,之前为缩小趋势,之后呈缓慢扩大的趋势;EU25区域差距在1993~2000年呈上升趋势,而在2000~2006年期间差距却明显下降。


欧盟区域经济趋同的实证分析, 邓翔, 路征 Jan 2009

欧盟区域经济趋同的实证分析, 邓翔, 路征

Zheng Lu (Chinese: 路征)

对欧盟自1987年之后人均实际GDP差异的研究表明,没有充分的证据支持欧盟经济存在趋同迹象。部分后起赶超国,如爱尔兰、芬兰有良好表现,而其他一些国家如意大利、德国则出现了结构性衰退和人均实际GDP增长的显著下滑。研究发现,欧盟15国与欧元区并不存在整体上的δ趋同,而β趋同检验显示初始人均GDP与增长率之间存在弱负相关关系,但2002年后,区域内人均实际GDP增长率有明显的趋同表现。


How Much Es In Csr, Anna Sienicka, Joanna Tyrowicz Jan 2009

How Much Es In Csr, Anna Sienicka, Joanna Tyrowicz

Joanna Tyrowicz

This paper approaches the problem of CSR in the context of social economy development in New Member States at the example of Poland. We explore the opportunities for companies to engage into socially beneficial undertakings with direct rather than indirect economic advantages. Namely, we demonstrate to what extent currently existing legal regulations enable bridging the world of civil society institutions with corporate world.

We suggest that even without specialized instruments adopted and implemented by CEECs governments, innova- tive inclusion solutions developed by civil society organizations may actually provide suficient incentives for companies in new member states to develop CSR. We ...


Exogenous Coalition Formation In The E-Marketplace Based On Geographical Proximity, Tomasz Michalak, Joanna Tyrowicz, Peter Mcburney, Michael Wooldridge Jan 2009

Exogenous Coalition Formation In The E-Marketplace Based On Geographical Proximity, Tomasz Michalak, Joanna Tyrowicz, Peter Mcburney, Michael Wooldridge

Joanna Tyrowicz

This paper considers a model for exogenous coalition formation in e-marketplaces. Using its informational advantage, an e-retailer creates coalitions of customers based on geographical proximity. Most of the literature regards this process as endogenous: a coalition leader among the buyers bundles eventual purchases together in order to obtain a better bargaining position. In contrast – and in response to what is typically observed in business practice – we analyse a situation in which an existing e-retailer exogenously forms customers’ coalitions. Results of this study are highly encouraging. Namely, we demonstrate that even under highly imperfect warehouse management schemes leading to contagion effects ...


Unemployment Convergence In Transition, Joanna Tyrowicz, Piotr Wojcik Jan 2009

Unemployment Convergence In Transition, Joanna Tyrowicz, Piotr Wojcik

Joanna Tyrowicz

In this paper an attempt is made to inquire the dynamics of regional unemployment rates in transition economies. We use policy relevant NUTS4 unemployment rates for transition economies characterised by both relatively intense (Poland, Slovaka) and relatively mild labour market hardships (Czech Republic). We apply diverse analytical techniques to seek traces of convergence, including beta- and sigma-convergence as well as time-series approach.

Transition economies typically experienced rapid growth of the unemployment rates due to profound restructuring. Naturally, these processes affected local labour markets asymmetrically, since regions were diversified with respect to industry composition and economic outlooks. Results in each of ...


Foreign Debt And Domestic Savings In Developing Countries, Luke Okafor, Joanna Tyrowicz Jan 2009

Foreign Debt And Domestic Savings In Developing Countries, Luke Okafor, Joanna Tyrowicz

Joanna Tyrowicz

This paper approaches the question of potential causality between foreign debt and domestic savings in the context of developing countries. Literature provides evidence in as far as foreign debt and development is concerned, but little attention was given so far to internal potential for capital formation. We provide a theoretical framework and test its relevance using 1975-2004 data for two groups of countries: sub-Saharan Africa and Latin America with the Caribbean. With the use of instrumental variables we find negative impact of foreign debt on domestic savings especially in the long run. The results are not susceptible to the choice ...


Is The Impact Really That High? The Effect Of Fdi In Transition, Jan Hagemejer, Joanna Tyrowicz Jan 2009

Is The Impact Really That High? The Effect Of Fdi In Transition, Jan Hagemejer, Joanna Tyrowicz

Joanna Tyrowicz

Literature is not clear on the effect of FDI on the economic performance in hosting countries. The analysed eects include productivity, propensity to export, access to financial markets, etc. Although foreign subsidiaries usually perform better than the average of the hosting economies, sometimes the selection eect is found to be considerable. The analysed eects In this paper we use a unique dataset based on accounting annual reports to the statistical authorities by all medium and large Polish enterprises over a period 1997-2006. We apply a propensity score matching technique to disentangle the effect of self-selection and FDI entry (treatment). We ...


When Eastern Labour Markets Enter Western Europe - Ceecs Labour Market Institutions Upon Euro Zone Accession, Joanna Tyrowicz Jan 2009

When Eastern Labour Markets Enter Western Europe - Ceecs Labour Market Institutions Upon Euro Zone Accession, Joanna Tyrowicz

Joanna Tyrowicz

This paper reviews the literature on the labour market institutions in European Union Member States in the context of monetary integration. Traditionally, labour markets are a key concept in the optimal currency area theory, playing the role of the only accommodation mechanism of asymmetric shocks after the monetary unification. There are several theoretical frameworks linking the institutional design of the labour market to the potential effectiveness of monetary policy in the context of currency areas. Many empirical studies addressed these issues too, yielding important policy implications for labour market reforms in the process of monetary unification. However, there seem to ...


Nonlinear Stochastic Convergence Analysis Of Regional Unemployment Rates In Poland, Joanna Tyrowicz, Piotr Wojcik Jan 2009

Nonlinear Stochastic Convergence Analysis Of Regional Unemployment Rates In Poland, Joanna Tyrowicz, Piotr Wojcik

Joanna Tyrowicz

This paper analyzes convergence of unemployment rates in Poland at NUTS4 level by testing nonlinear convergence, applying the modified KSS-CHLL for each pair of territorial units. The results suggest that actually the convergence is a rare phenomenon and occurs only in 1916 cases out of potential over 70 000 combinations. This paper inquires what systematic reasons contribute to this phenomenon.

There are some circumstances under which unemployment convergence should be more awaited than in the others. These include sharing a higher level territorial authority, experiencing similar labour market hardship or sharing the same structural characteristics. For each of these three ...


Blame No One? Investment Decisions Of The Polish Stock-Listed Companies, Joanna Tyrowicz Jan 2009

Blame No One? Investment Decisions Of The Polish Stock-Listed Companies, Joanna Tyrowicz

Joanna Tyrowicz

It is often raised that enterprises in transition countries are cursed with credit constraints and insufficient capital. Regardless of whether this belief holds for the whole of the economy, the Agency Theory provides a useful both theoretical and empirical framework helping to verify the efficiency of investment decisions in case of companies for which 'objective' future cash-flow valuation is available. The assertion of managerial discretion has been verified empirically for many different countries with the analytical background provided by user cost of capital and Tobin's Q theories. This paper’s contribution is the analysis of the Polish stock-listed companies ...


Labour Market Racial Discrimination In South Africa Revisited, Joanna Tyrowicz, Maciej Szelewicki Jan 2009

Labour Market Racial Discrimination In South Africa Revisited, Joanna Tyrowicz, Maciej Szelewicki

Joanna Tyrowicz

Discrimination is a significant issue in labour market economics across developed as well as developing countries. In this paper we inquire the actual size of wage discrimination in the Republic of Soutn Africa, accounting for large differences in endowments. We apply the Oaxaca-Blinder decomposition as well as propensity score matching to adequately determine the size of the pay gap. Although the size of the absolute racial pay gap is enormous, amounting for more than 500%, the actual estimated effect non-attributable to other factors ranges between 45%-55%. This estimator however assumes homogenous discrimination across the wage distribution, while data suggest ...


(In)Efficiency Of Matching - The Case Of A Post-Transition Economy, Joanna Tyrowicz, Tomasz Jeruzalski Jan 2009

(In)Efficiency Of Matching - The Case Of A Post-Transition Economy, Joanna Tyrowicz, Tomasz Jeruzalski

Joanna Tyrowicz

This paper approaches the question of efficiency in job placement using regional data for Polish regions (policy relevant NUTS 4 level) over the time span of 2000-2008. Using a unique data set we estimate the matching function using stochastic frontier as well as difference-in-difference estimators. We use also managed to combine this unique data set with another unique source of data on the ALMPs

coverage, unemployment structure across time and regions as well as the individual capacity of local labour offices. We use these data to explain the exceptional variation in estimated efficiency scores.

Our findings suggest that matching abilities ...


Competition Law And The Economy In The Russian Federation, 1990-2006, Reza Rajabiun Jan 2009

Competition Law And The Economy In The Russian Federation, 1990-2006, Reza Rajabiun

Reza Rajabiun

Most developing and transition countries adopted statutes prohibiting anticompetitive agreements and abusive practices during the 1980's and 1990's. The effectiveness of these laws is nevertheless widely debated. This paper contributes to the literature by conducting an event study of the adoption of Russian competition laws in the early years of transition, the subsequent economic developments and the legislative reform process of 2002-2006. An examination of the substantive prohibitions and enforcement data reveals that Russian competition laws relied on complex standards and imposed weak constraints on anticompetitive practices. The more recent shift to simpler and more predictable per se ...


Competition Law As Development Policy: Evidence From Poland, Reza Rajabiun Jan 2009

Competition Law As Development Policy: Evidence From Poland, Reza Rajabiun

Reza Rajabiun

The relationship between the design of competition laws and economic outcomes remains the subject of considerable controversy in both law and economics. Recent cross-national studies suggest that effective legal constraints against anticompetitive practices can enhance prospects for economic development by increasing the number of market participants and the quality of broader political and economic institutions. This paper explores the linkages between regulatory constraints against anticompetitive practices and the efficiency of market mechanisms by focusing on the experience in Poland between the collapse of central planning and regulatory harmonization pursuant to European Union accession. The analysis suggests that per se prohibitions ...
