An Empirical Analysis of the Credit-Output Relationship: Evidence from Peru

This paper investigates the empirical relationship between credit and output in Peru. The analysis is based on the estimation of vector error correction models and the identification of structural shocks. The models considered include real output, real credit growth (in domestic currency, foreign currency and both), and terms of trade. Using quarterly data for the period 1994-2011, the results suggest that real credit growth contain useful information to understand the evolution of the non-deterministic component of real output. In particular, the results show that: (i) there exist a stable long-run relationship between real credit growth, output and terms of trade, (ii) real credit growth is useful in forecasting output in the long-run, and (iii) a structural permanent shock in real credit has positive permanent effects on output. Therefore, credit aggregates could be useful as indicator variables for policymakers.Credit growth, output growth, vector error correction models, structural shocks.

A Quantitative General Equilibrium Approach to Migration, Remittances and Brain Drain

Developing countries have experienced an outstanding outflow of skilled workers (brain- drain) over the last several decades. Additionally, migrants tend to be tied to their country of birth, since they send a large amount of remittances to their relatives. Furthermore, migration is not permanent, since a considerable number of workers return to their country of birth after a migration spell. In this paper we develop a model that is consistent with these facts. We use our model to address some important issues in the migration literature from a theoretical perspective. We study the general equilibrium effects of migration, its long-term effects, and its welfare effects, and we see whether the joint effect of return migration and remittances is strong enough to offset the effects of skilled migration. Finally, we evaluate the effectiveness of policy interventions that attempts to offset the effects of a brain drain.Migration, General Equilibrium, Brain drain, Remittances, Heterogeneous Agents

Monetary Policy and Stock Market Booms

Historical data and model simulations support the following conclusion. Inflation is low during stock market booms, so that an interest rate rule that is too narrowly focused on inflation destabilizes asset markets and the broader economy. Adjustments to the interest rate rule can remove this source of welfare-reducing instability. For example, allowing an independent role for credit growth (beyond its role in constructing the inflation forecast) would reduce the volatility of output and asset prices.inflation targeting, sticky prices, sticky wages, stock price boom, DSGE model, New Keynesian model, news, interest rate rule

Employment Protection and Business Cycles in Emerging Economies

We build a small open economy, real business cycle model with labor market frictions to evaluate the role of employment protection in shaping business cycles in emerging economies. The model features matching frictions and an endogenous selection effect by which inefficient jobs are destroyed in recessions. In a quantitative version of the model calibrated to the Mexican economy we find that reducing separation costs to a level consistent with developed economies would reduce output volatility by 15 percent. We also use the model to analyze the Mexican crisis episode of 2008 and conclude that an economy with lower separation costs would have experienced a smaller drop in output and in measured total factor productivity with no significant change in aggregate employment.

The Distribution of the Size of Price Changes

Different theories of price stickiness have distinct implications on the number of modes in the distribution of price changes. We formally test for the number of modes in the price change distribution of 36 supermarkets, spanning 22 countries and 5 continents. We present results for three modality tests: the two best-known tests in the statistical literature, Hartigan's Dip and Silverman's Bandwidth, and a test designed in this paper, called the Proportional Mass test (PM). Three main results are uncovered. First, when the traditional tests are used, unimodality is rejected in about 90 percent of the retailers. When we used the PM test, which reduces the impact of smaller modes in the distribution and can be applied to test for modality around zero percent, we still reject unimodality in two thirds of the supermarkets. Second, category-level heterogeneity can account for about half of the PM test's rejections of unimodality. Finally, a simulation of the model in Alvarez, Lippi, and Paciello (2010) shows that the data is consistent a combination of both time and state-dependent pricing behaviors.

Some stylized facts of returns in the foreign exchange and stock markets in Peru

Some stylized facts for foreign exchange and stock market returns are explored using statistical methods. Formal statistics for testing presence of autocorrelation, asymmetry, and other deviations from normality is applied to these financial returns. Dynamic correlations and different kernel estimations and approximations of the empirical distributions are also under scrutiny. Furthermore, dynamic analysis of mean, standard deviation, skewness and kurtosis are also performed to evaluate time-varying properties in return distributions. Main results reveal different sources and types of non-normality in the return distributions in both markets. Left fat tails, excess kurtosis, return clustering and unconditional time-varying moments show important deviations from normality. Identifiable volatility cycles in both forex and stock markets are associated to common macro financial uncertainty events.Non-Normal Distributions, Stock Market Returns, Foreign Exchange Market Returns.

Measuring the Effects of Monetary Policy Using Market Expectations

In order to quantify the effects of monetary policy, this paper employs an alternative empirical measure of monetary policy shocks based on market expectations obtained from media and survey information in Peru. Using monthly data for the period 2003-2011, we use the proposed measure as a variable representing exogenous variation in monetary policy and evaluate its dynamic impact on output and prices. The results show a coherent picture of the effects of monetary policy compared to alternative approaches in terms of both the magnitude and the timing of the effects.Monetary policy shocks, media, survey

Dedollarization and financial robustness

This paper evaluates the qualitative and quantitative implications of financial dedollarization of firms' liabilities on real aggregates in a small open economy model. We extend the standard Cespedes, Chang, and Velasco (2004) model by allowing entrepreneurs borrow in both foreign and domestic currency so as to finance firms' capital needs. A real depreciation reduces the value of firms' net worth whenever there is a currency mismatch in their balance sheets. Under flexible exchange rates, a lower degree of dollarization lessens the negative impact on output and investment, since there is a smaller increase in the cost of external borrowing. The quantitative results show that the balance sheet channel accounts for about 70 percent of the output and investment drop in Peru following the Russian Crisis, and a reduction in debt dollarization would have reduced output drop in 0.9 percentage points of GDP.Small open economy, balance sheet eects, dollarization

Liquidity Shocks and the Business Cycle

This paper studies the properties of an economy subject to random liquidity shocks. As in Kiyotaki and Moore [2008], liquidity shocks affect the ease with which equity can be used as to finance the down-payment for new investment projects. We obtain a liquidity frontier which separates the state-space into two regions (liquidity constrained and unconstrained). In the unconstrained region, the economy behaves according to the dynamics of the standard real business cycle model. Below the frontier, liquidity shocks have the effects of investment shocks. In this region, investment is under-efficient and there is a wedge between the price of equity and the real cost of capital. As with investment shocks, we argue that liquidity shocks are not an important source of business cycle fluctuations in absence of other frictions affecting the labor market.Business Cycle, Asset Pricing, Liquidity
