Effects of Fiscal Consolidation in the Czech Republic
Description: This paper uses the IMF’s Global Integrated Monetary and Fiscal Model (GIMF) to assess the impact of fiscal consolidation on the Czech economy. Its contribution is threefold. First, it provides estimates of dynamic fiscal multipliers for a variety of fiscal instruments (tax and expenditure), consolidation durations, assumptions about credibility, and monetary policy responses. Second, the paper evaluates the impact on the economy of tightening measures envisaged in the 2011 budget. Third, the paper considers alternative packages for consolidation beyond 2011 to achieve the government’s balanced budget target by 2016 and identifies which forms of adjustment are more "growth-friendly".

Reviving the Competitive Storage Model: A Holistic Approach to Food Commodity Prices
Description: We revive in this paper the empirical relevance of the competitive storage model by taking a holistic approach to food commodity prices. We augment the seminal Deaton and Laroque (1992, 1996) model by incorporating more comprehensive and realistic supply and demand factors: output and demand trends, shocks to the yield, and time-varying interest rates. While the computational burden increases exponentially, the augmented model succeeds in replicating all four key patterns of food commodity prices. Our simulation and comparative statics also show that (i) the long-run declining trend of food prices may come to a halt or even reverse due to the shifting balance between supply and demand; (ii) short-run price fluctuations are mainly attributable to sizeable, though low-probability, shocks to output such as inclement weather; and (iii) the impact of monetary policy, though small in normal times, is nonlinear and asymmetric, and can become large if the real rate passes a certain threshold.

Leadership Contestability, Monopolistic Rents and Growth
Description: I construct an endogenous growth model where R&D is carried out at the industry level in a game of innovation between leaders and followers. Innovation costs for followers are assumed to increase with the technological lag from leaders. We obtain three results that contrast with standard Schumpeterian models, such as Aghion and Howitt (1992). First, leaders may innovate in equilibrium, in an attempt to force followers out of the innovation game. Second, policies (such as patents) that allow for strong protections of monopolies can reduce the steady state growth rate of the economy. Third, multiple equilibria arise when monopolies' protection is large.

How Strong are Fiscal Multipliers in the GCC?
Description: The effectiveness of fiscal policy in smoothing the impact of shocks depends critically on the size of fiscal multipliers. This is particularly relevant for the GCC countries given the need for fiscal policy to cushion the economy from large terms of trade shocks in the absence of an independent monetary policy and where fiscal multipliers could be weak dues to substantial leakages through remittances and imports. The paper provides estimates of the size of fiscal multipliers using a variety of models. The focus is on government spending since tax revenues are small. The long-run multiplier estimates vary in the 0.3-0.7 range for current expenditure and 0.6-1.1 for capital spending, depending on the particular specification and estimation method chosen. These estimates fall within the range of fiscal multiplier estimates in the literature for non-oil emerging markets.

Imperfect Information and Saving in a Small Open Economy
Description: Emerging markets are more volatile and face different types of shocks, in size and nature, compared to their developed counterparts. Accurate identification of the stochastic properties of shocks is difficult. We show evidence suggesting that uncertainty about the underlying stochastic process is present in commodity prices. In addition, we build a dynamic stochastic general equilibrium model with informational frictions, which explicitly considers uncertainty about the nature of shocks. When formulating expectations, the economy assigns some probability to the shocks being temporary even if they are actually permanent. Parameter instability in the stochastic process implies that optimal saving levels (debt holdings) should be higher (lower) compared to a process with fixed parameters. Imperfect information about the nature of shocks matters when commodity GDP shares are high. Thus, economic policies based on misperception of the underlying regime can lead to substantial over/under saving with important associated costs.

Inflation Uncertainty and Relative Price Variability in WAEMU Countries
Description: Using a consistent dataset and methodology for all eight member countries of the West African Economic and Monetary Union (WAEMU) from 1994 to 2009, this paper provides evidence of the two major channels for real effects of inflation: inflation uncertainty and relative price variability. In line with theory and most evidence for advanced and emerging market economies, higher inflation increases inflation uncertainty and relative price variability in all WAEMU countries. However, the pattern, magnitude and timing of these two channels vary considerably by country. The findings raise several policy issues for future research.

The Impact of Legislation on Credit Risk—Comparative Evidence From the United States, the United Kingdom and Germany
Description: This study investigates the link between bankruptcy and security legislation and potential credit losses faced by banks based on a cross-country study for the United States (US), the United Kingdom (UK) and Germany. Focusing on corporate credit, we find that legislation produces the highest credit risk in the US, followed by Germany, while UK law is found to be most favorable for banks. US banks gains from the higher number of informal restructurings (without losses) but lose from the low level of recovery in formal proceedings. German banks demand more credit risk mitigants than UK and US banks do, but still recover less than do UK banks. To be at par with UK banks, US banks would have to recover more than twice as much in formal proceedings, while German proceedings would have to be shortened by about one half.

Taxing Financial Transactions: Issues and Evidence
Description: In reaction to the recent financial crisis, increased attention has recently been given to financial transaction taxes (FTTs) as a means of (1) raising revenue for a variety of possible purposes and/or (2) helping to curb financial market excesses. This paper reviews existing theory and evidence on the efficacy of an FTT in fulfilling those tasks, on its potential impact, and on key issues to be faced in designing taxes of this kind.

Bank Ownership and the Effects of Financial Liberalization: Evidence from India
Description: Do financial sector reforms necessarily result in expansion of credit to the private sector? How does bank ownership affect the availability of credit to the private sector? Empirical evidence is somewhat mixed on these issues. We use the Indian experience with liberalization of the financial sector to inform this debate. Using bank-level data from 1991-2007, we ask whether public and private banks deployed resources freed up by reduced state preemption to increase credit to the private sector. We find that even after liberalization, public banks allocated a larger share of their assets to government securities than did private banks. Crucially, we also find that public banks were more responsive in allocating relatively more resources to finance the fiscal deficit even during periods when state pre-emption (measured in terms of the requirement to hold government securities as a share of assets) formally declined. These findings suggest that in developing countries, where alternative channels of financing may be limited, government ownership of banks, combined with high fiscal deficits, may limit the gains from financial liberalization.

The Real Effects of Financial Sector Interventions During Crises
Description: We collect new data to assess the importance of supply-side credit market frictions by studying the impact of financial sector recapitalization packages on the growth performance of firms in a large cross-section of 50 countries during the recent crisis. We develop an identification strategy that uses the financial crisis as a shock to credit supply and exploits exogenous variation in the degree to which firms depend on external financing for investment needs, and focus on policy interventions aimed at alleviating the bank capital crunch. We find that the growth of firms dependent on external financing is disproportionately positively affected by bank recapitalization policies, and that this effect is quantitatively important and robust to controlling for other financial sector support policies. We also find that fiscal policy disproportionately boosted growth of firms more dependent on external financing. These results provide new evidence of a quantitatively important role of credit market frictions in influencing real economic activity.
