Do Bilateral Investment Treaties Attract Foreign Direct Investment? Only a Bit ... and They Could Bite
(World Bank, Washington, DC, 2003-08)Touted as an important commitment device that attracts foreign investors, the number of bilateral investment treaties (BITs) ratified by developing countries has grown dramatically. The author tests empirically whether BITs have actually had an important role in increasing the foreign direct investment (FDI) flows to signatory countries. While half of OECD FDI into developing countries by 2000 was covered by a BIT, this increase is accounted for by additional country pairs entering into agreements rather than signatory hosts gaining significant additional FDI. The results also indicate that such treaties act more as complements than as substitutes for good institutional quality and local property rights, the rationale often cited by developing countries for ratifying BITs. The relevance of these findings is heightened not only by the proliferation of such treaties, but by recent high profile legal cases. These cases show that the rights given to foreign investors may not only exceed those enjoyed by domestic investors, but expose policymakers to potentially large-scale liabilities and curtail the feasibility of different reform options. Formalizing relationships and protecting against dynamic inconsistency problems are still important, but the results should caution policymakers to look closely at the terms of agreements. -

Creative Destruction and Policy Reforms : Changing Productivity Effects of Firm Turnoverin Moroccan Manufacturing
( 2009-10-01)How important is firm turnover to national productivity growth? The literature points to the contribution of creative destruction being strongest in more developed countries or where market institutions are strongest. This paper looks at the case of Morocco, spanning 16 years, during which reform initiatives aiming to strengthen market forces were introduced. The paper argues that it is important to take into account i) the timing of how decompositions are structured (capturing the effects of high growth among young firms as part of the benefit of increased entry) and ii) the additional indirect impacts of firm dynamics on agglomeration externalities and competition. The paper shows there are striking differences in the productivity paths of entering and exiting firms compared with incumbents, and that restricting the time horizon of productivity decompositions to the actual year of entry or exit underestimates the productivity effects of turnover. Although it has been hypothesized that conducting decompositions over longer horizons would increase the positive contribution of net turnover, this is not the case in Morocco as losses from exiting firms rise too. Nor has the net contribution of turnover increased with market reforms; if anything, the contribution has declined over time. But the allocation of resources has improved. Both technical and allocative efficiency have risen since the mid-1990s. The paper also shows that firm turnover affects productivity through additional channels. It is closely correlated with measures of agglomeration that are associated with higher rates of exit among unproductive firms, and turnover itself is positively associated with subsequent productivity growth of incumbents. -

Big Constraints to Small Firms’ Growth? Business Environment and Employment Growth across Firms
( 2009-08-01)Using data on more than 56,000 enterprises in 90 countries, this paper finds that objective conditions in the business environment vary substantially across firms of different sizes and that there are important non-linearities in their impact on employment growth. The paper focuses on four areas: access to finance, business regulations, corruption, and infrastructure. The results, particularly on the impacts of finance and corruption on growth, depend on whether and how the analysis accounts for the possible endogeneity of the business environment. Controlling for endogeneity revises the finding that small firms benefit most from access to finance, particularly for sources of finance associated with investment and growth. The findings are also sensitive to how small is defined. Differentiating micro (less than 10 employees) from other small firms shows that, while small firms can be disadvantaged in such an environment, micro firms tend to be proportionally less affected by a weak business climate and, on occasion, it can help them to grow. Overall, allowing different size classifications provides insights into the impact of the business environment that are lost in more aggregate analyses. -

Mind the Neighbors : The Impact of Productivity and Location on Firm Turnover
( 2009-10-01)This paper examines the impact of firm productivity and local industrial structure on firm entry and exit in Morocco between 1985 and 2001. There is strong evidence of productivity exerting a market-cleansing role. Less productive firms are found to be more likely to exit - and locations with more productive firms attract higher rates of new firm entry. The effect of productivity operates not only in an absolute sense; a firm s relative productivity or distance to the local sector frontier matters too. First, large productivity gaps are associated with higher rates of exit, while new firms are attracted to locations with small productivity gaps. Second, local competition increases the probability of exit, although it does not encourage entry. Third, there is evidence of scale or agglomeration effects that increase firm turnover. Fourth, measures of sector diversity are not associated with lower turnover. Fifth, the geographic level at which agglomeration and competition effects are defined matters differently for exit than entry. For exit, the provincial measures are strong, while those for communes are weaker. For entry, it is the local productivity at the commune level that is more significant. This implies that competitive pressures are less geographically constrained while the potential benefits of agglomeration and spill-overs are indeed more local.
