Remittances in Pakistan: Why have they gone up, and why Aren't they coming down?
Description: The flow of workers' remittances to Pakistan has more than quadrupled in the last eight years and it shows no sign of slowing down, despite the economic downturn in the Gulf Cooperation Council (GCC) and other important host countries for Pakistani workers. This paper analyses the forces that have driven remittance flows to Pakistan in recent years. The main conclusions are: (i) the growth in the inflow of workers' remittances to Pakistan is in large part due to an increase in worker migration; (ii) higher skill levels of migrating workers have helped to boost remittances; (iii) other imporant determinants of remittances to Pakistan are agriculture output and the relative yield on investments in the host and home countries.

Shocks, Financial Dependence, and Efficiency: Evidence From U.S. and Canadian Industries
Description: The paper investigates how changes in industries' funding costs affect total factor productivity (TFP) growth. Based on panel regressions using 31 U.S. and Canadian industries between 1991 and 2007, and using industries' dependence on external funding as an identification mechanism, we show that increases in the cost of funds have a statistically significant and economically meaningful negative impact on TFP growth. This effect is, however, non-monotonic across sectors with different degrees of dependence on external finance. Our findings cannot be explained by either increasing returns to scale or factor hoarding, as results are not sensitive to controlling for industry size and our calculations account for changes in factor utilization. The paper presents a theoretical model that produces the observed non-monotonic effect of financial shocks on TFP growth and suggests that financial shocks distort the allocation of factors across firms even within an industry, thus reducing TFP growth.

Institutional Cash Pools and the Triffin Dilemma of the U.S. Banking System
Description: Through the profiling of institutional cash pools, this paper explains the rise of the "shadow" banking system from a demand-side perspective. Explaining the rise of shadow banking from this angle paints a very different picture than the supply-side angle that views it as a story of banks' funding preferences and arbitrage. Institutional cash pools prefer to avoid too much unsecured exposure to banks even through insured deposits. Short-term government guaranteed securities are the next best choice, but their supply is insufficient. The shadow banking system arose to fill this vacuum. One way to manage the size of the shadow banking system is by adopting the supply management of Treasury bills as a macroprudential tool.

FDI from BRICs to LICs: Emerging Growth Driver?
Description: Despite the rapid increase in FDI flows to LICs, there have been relatively few studies that have specifically examined these flows. This paper attempts to partially fill the void by throwing light on one particularly dynamic aspect of global FDI-flows from Brazil, Russia, India and China (BRICs). The paper finds that official data sources undoubtedly underestimate the volume and scope of FDI flows as many small and medium-sized enterprises (SMEs) do not always register their investment. As a result, while it is difficult to estimate accurately the growth impact of BRIC FDI, there is case study evidence that it is increasingly significant. Second, while initial investment, mostly by state-owned companies, has often been destined for natural resource industries, over time, investment has been spreading to agriculture, manufacturing, and service industries (e.g., telecommunications). Third, FDI from BRICs flows into many non resource-rich countries in LICs and plays a significant role in growth in those countries.

Determinants of Interest Rate Pass-Through: Do Macroeconomic Conditions and Financial Market Structure Matter?
Description: Numerous empirical studies have found that the strength of the interest rate pass-through varies markedly across countries and markets. The causes of such heterogeneity have attracted considerably less attention so far. Unlike other studies that mainly focus on small groups of mostly developed and emerging markets in the same region, this paper expands the cross-sectional coverage to 70 countries from all regions, including low income, emerging and developed countries. It uses a wide range of macroeconomic and financial market structure variables to uncover structural determinants of pass-through. The paper finds that per capita GDP and inflation have positive effects on pass-through, while market volatility has a negative effect. Among financial market variables exchange rate flexibility, credit quality, overhead costs, and banking competition were found to strengthen pass-through, whereas excess banking liquidity to impede it.

The Impact of the Global Financial Crisison Microfinance and Policy Implications
Description: The global financial crisis affected microfinance institutions (MFIs) as lending growth was constrained by scarcer borrowing opportunities, while the economic slowdown negatively impacted asset quality and profitability. It also brought to the fore the relatively high interest rates that MFIs charge to their (low-income) customers. This paper revisits the issue of systemic risk of MFIs, and finds that contrary to the evidence before the crisis, MFI performance is correlated not only to domestic economic conditions but also to changes in international capital markets. It also presents an empirical analysis of lending rates with the purpose of informing policy decisions, and finds that loan sizes, productivity, and MFI age contribute to explain differences in lending rate levels. This suggest that regulation (and policies) promoting MFI competition, and innovation in lending technologies have a better chance to result in decreased lending rates.

The Quest for Higher Growth in the WAEMU Region: The Role of Accelerations and Decelerations
Description: With the exception of Burkina Faso and Mali, the growth experience for WAEMU countries has been disappointing, even when compared to other sub-Saharan African (SSA) countries. The main objective of the paper is to investigate why the quest for a growth takeoff has been more elusive in the WAEMU countries compared to other SSA countries. To do this, the paper focuses on the determinants of growth accelerations and decelerations in SSA and the WAEMU. It finds that the variables most closely associated with growth accelerations and decelerations in SSA are changes in terms of trade, private investment, civil tension, real exchange rates, and inflation. Second, as found elsewhere in the literature, there is a certain asymmetry between accelerations and decelerations, in both frequency and determinants, and that the WAEMU region is quite different from the rest of SSA.

Democratic Accountability, Deficit Bias, and Independent Fiscal Agencies
Description: Despite growing interest among policymakers, there is no theory of independent fiscal institutions. The emerging literature on "fiscal councils" typically makes informal parallels with the theory of central bank independence, but a very simple formal example shows that such a shortcut is flawed. The paper then illustrates key features of a model of independent fiscal agencies, and in particular the need (1) to incorporate the intrinsically political nature of fiscal policy - which precludes credible delegation of instruments to unelected decisionmakers - and (2) to focus on characterizing "commitment technologies" likely to credibly increase fiscal discipline.

Country Insurance Using Financial Instruments
Description: The availability of financial instruments related to indices that track global financial conditions and risk appetite can potentially offer countries alternative options to insure against external shocks. This paper shows that while these instruments can explain much of the in-sample variation in borrowing spreads, this fails to materialize in hedging strategies that work well out-of-sample during tranquil times. However, positions on instruments such as those tracking the US High Yield Spread, the VIX, and especially other emerging market CDS spreads can substantially offset adverse movements in own spreads during times of systemic crises. Moreover, high risk countries seem to gain more, as their underlying weaknesses makes them more vulnerable to external shocks. Overall, the limited value in tranquil times, coupled with political economy arguments and innovation costs could justify the limited interest for this type of hedging in practice

Rainfall, Financial Development, and Remittances: Evidence From Sub-Saharan Africa
Description: We use annual variation in rainfall to examine the effects that exogenous, transitory income shocks have on remittances in a panel of 42 Sub-Saharan African countries during the period 1960-2007. Our main finding is that these income shocks have a significant positive effect on remittances, but that the effect is significantly decreasing in the share of domestic credit to GDP. So much so, that at high levels of credit to GDP transitory increases in income had a significant negative effect on remittances. Our findings are consistent with the view that remittances take advantage of unexploited domestic investment opportunities that can exist due to domestic credit market frictions. Our findings also support the view that when barriers to financial flows are low, remittances effectively provide insurance against transitory income shocks.
