    Regulation, Trade and Productivity in Romania : An Empirical Assessment
    (World Bank, Washington, DC, 2013-06) De Rosa, Donato; Iootty, Mariana; Pirlea, Ana Florina
    Inappropriate regulation can influence productivity performance by affecting incentives to invest and adopt new technologies, as well as by directly curbing competitive pressures. Results of a labor productivity growth model for European countries suggest that improving the regulatory environment -- proxied by the Worldwide Governance Indicators regulatory quality indicator -- and boosting effective exposure to competition through increasing trade integration -- expressed as the ratio of exports plus imports to gross domestic product -- have positive effects on productivity growth. In Romania a 10 percent increase in openness to global trade over 1995-2010 would have boosted productivity growth by 9.7 percent per year. A 10 percent increase in openness to European Union trade, in particular, would have led to an annual increase in productivity of 7 percent. Realizing the benefits from trade integration depends to some extent on regulation. In this regard, the effects of regulation on productivity growth are found to be positive, regardless of the indicator used to measure regulation, and both through direct and indirect channels (by increasing the speed at which a country catches up with productivity leaders). Simulation results also show how countries with different levels of regulatory quality would benefit from a regulatory improvement: had Romania improved its regulatory environment to the same level as Denmark in 2010, its annual productivity growth would have been 14 percent higher over 1995-2010.

    Will the Crisis Affect the Economic Recovery in Eastern European Countries? Evidence from Firm Level Data
    (2010-04-01) Correa, Paulo; Iootty, Mariana
    Two sources of growth are firm learning and innovation. Using a unique panel data for 1,686 firms in six countries (Bulgaria, Hungary, Latvia, Lithuania, Romania, and Turkey), this paper applies panel data estimators and Juhn-Murphy Pierce decomposition in order to identify the effects of the global economic crisis on sales growth of innovative and young enterprises in Eastern European countries. The results show that innovative and young firms were significantly more affected by the crisis than non innovative and older enterprises. The authors interpret these results as an indication that the achievement of pre-crisis growth rates in those countries may be difficult.

    Georgia Competitive Industries Preliminary Sector Diagnostic
    (World Bank, Washington, DC, 2013-06) Onugha, Ifeyinwa; Iootty, Mariana; Kilroy, Austin; Palmade, Vincent
    As a small and open economy, Georgia's growth prospects are directly linked to its ability to produce and sell goods and services competitively in the global marketplace. The World Bank Georgia Competitive Industries Technical Assistance Project has been launched in February 2013 in response to the December 19, 2012 letter of the Ministry of economy and sustainable development of Georgia with the request to get the Bank's support in diagnoses of trade competitiveness and identification of a road map for reform to enhance Georgia's export growth and competitiveness. The project is envisioned as a three phase program, that comprises: February-June 2013 analytical and technical assistance support, including diagnostic of trade competitiveness and constraints to export growth, and competitive industries sector diagnostic report, supported by extensive discussions through a series of workshops, private and public sector interviews, discussions and a large 2-day seminar on February 28-March 1, 2013; July-December 2013-deep dive analysis of selected competitive industries and development of a reform road map to support Georgia's competiveness strategy; and from January 2013-reform implementation, supported by the Bank's technical assistance, policy advice and lending operations. The report is prepared on the basis of the competitive industries sector prioritisation framework. The report incorporates ideas and recommendations received during February 28-March 1, 2013 seminar and several smaller workshops and brainstorming sessions held in March-May 2013. Export led growth provides also a strong motivation to reform the domestic industries which will continue to account for the vast majority of employment. Georgia's main domestic industries include agriculture, retail/wholesale, construction, transportation, health and education. Since economic growth is accounted for by productivity improvements by workers in all industries, export-led growth can play a key role in raising these productivity levels.

    Corporate Market Power in Romania: Assessing Recent Trends, Drivers, and Implications for Competition
    (World Bank, Washington, DC, 2020-12) Pop, Georgiana; Iootty, Mariana; Pena, Jorge
    This paper explores firm-level heterogeneity to identify the underlying drivers of market power trends in Romania and the implications for competition and economic growth. The results show that the (sales-weighted) average markup in Romania increased by around 15 percent between 2008 and 2017. A key driving force behind this aggregate trend was the ability of a small fraction of firms -- the top decile firms in the markup distribution -- to increase their markups. These firms do not seem to follow the typical superstar firms' profile: they are smaller, less efficient, and less likely to invest in intangible assets than other firms in the markup distribution and overrepresented in less knowledge-intensive service sectors (for example, the retail and trade sector). This suggests that the increase in markups in Romania might be associated with an environment that is less conducive to competition. A decomposition exercise shows that the increase in aggregate markups has been driven mostly by incumbents rather than new entrants and exiting firms, which could be interpreted as a sign of consolidation of market power among existing firms. The paper also finds that certain firm characteristics matter to explain differences in markup performance: size, age, research and development profile, export propensity, location, and especially ownership. Further, the paper shows that additional productivity dividends are associated with increased competition in Romania. Overall, these findings illustrate potential policy angles that need to be tackled to enhance market contestability and boost productivity growth, such as addressing regulations that restrict entry and rivalry in the retail trade sector, which concentrates a substantial proportion of high-markup firms, as well as promoting competitive neutrality across markets where public and private actors compete.

    Assessing Innovation Patterns and Constraints in Developing East Asia: An Introductory Analysis
    (World Bank, Washington, DC, 2019-01) Iootty, Mariana
    This paper sheds light on key innovation patterns and constraints within a selected set of developing East Asian countries (Cambodia, China, Indonesia, the Lao People’s Democratic Republic, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam). It follows a comprehensive approach about national innovation systems while highlighting the supply and demand dimensions of innovation as well as the markets where firms make accumulation decisions for different forms of capital (knowledge capital, human capital. and physical capital). The paper presents a set of empirical exercises drawing from various data sets. The results corroborate the idea of the importance of adopting a broad view of innovation policy and investing in missing complementary factors. Although investment in research and development is key to boost innovation, it is also crucial to have business and regulatory environments that are conducive to overall firm performance and capital accumulation (not only knowledge capital), as they are expected to improve innovation returns. In addition, the results suggest that other innovation inputs aside from research and development matter for innovation activities, such as training for innovative activities, acquisition/licensing of technology, and managerial practices.

    Productivity Growth in Europe
    (World Bank, Washington, DC, 2013-04) Dall'Olio, Andrea; Iootty, Mariana; Kanehira, Naoto; Saliola, Federica
    This paper tests whether structural or firm-specific characteristics contributed more to (labor) productivity growth in the European Union between 2003 and 2008. It combines the Amadeus firm-level data on productivity and firm characteristics with country-level data describing regulatory environments from the World Bank's Doing Business surveys, foreign direct investment data from Eurostat, infrastructure quality assessments from the Global Competitiveness Report, and credit availability from the World Development Indicators. It finds that among the 12 newest members of the European Union, country characteristics are most important for firm productivity growth, particularly the stock of inward foreign direct investment and the availability of credit. By contrast, among the more developed 15 elder European Union member countries, firm-level characteristics, such as industry, size, and international affiliation, are most important for growth. The quality of the regulatory environment, measured by Doing Business indicators, is importantly correlated with productivity growth in all cases. This finding suggests that European Union nations can realize significant benefits from improving regulations and encouraging inward and outward foreign direct investment.

    Are Natural Resources Cursed? An Investigation of the Dynamic Effects of Resource Dependence on Institutional Quality
    (World Bank, Washington, DC, 2012-07) De Rosa, Donato; Iootty, Mariana
    This paper examines whether natural resource dependence has a negative influence on various indicators of institutional quality when controlling for the potential effects of other geographic, economic and cultural initial conditions. Analysis of a panel of countries from 1996 to 2010 indicates that a high degree of resource dependence, measured as the share of mineral fuel exports in a country's total exports, is associated with worse government effectiveness, as well as with reduced levels of competition across the economy. Furthermore, estimation of long-run elasticities suggests that government effectiveness and the intensity of domestic competition decrease over time as the dependence on natural resources increases. An illustration of the Russian case shows that the negative effects accumulate in the long run, leading to a worse deterioration of government effectiveness in Russia than in Canada, a country with a comparable resource endowment but far better overall institutional quality. This result is corroborated by a significant negative correlation found between regional resource dependence and an indicator of regulatory capture in Russian regions, which indicates that the regulatory environment is more likely to be subverted in regions that are more dependent on extractive industries. Overall, the findings would be consistent with a situation in which a generally weak institutional environment would allow resource interests to wield the bidding power accruing from export revenues to subvert the content of laws and regulations, as well as their enforcement. The fact that this is associated with negative externalities for the rest of the economy, notably by undermining a level playing field across non-resource sectors, sheds light on a potential channel for the resource curse.
