    Sending the pork home: Birth town bias in transfers to Italian municipalities

    Abstract

    We ask whether the birthplaces of Italian members of Parliament are favoured in the allocation of central government transfers. Using a panel of municipalities for the years between 1994 and 2006, we find that municipal governments of legislators' birth towns receive larger transfers per capita. Exploiting the fact that some birth towns are outside of the district of election, we conclude that this result cannot be driven by re-election incentives. On the contrary, we show that these incentives discourage legislators from diverting resources to their birthplace. We present evidence that those transfers are a way for a politician to prepare the ground for a post-congressional career in the municipal administration.

    Why did sponsor banks rescue their sivs? A signaling model of rescues

    Abstract

    At the beginning of the past financial crisis sponsoring banks rescued their structured investment vehicles (SIVs) despite of lack of contractual obligation to do so. I show that this outcome may arise as the equilibrium of a signaling game between banks and their debt investors when a negative shock affects the correlated asset returns of a fraction of banks and their sponsored vehicles. The rescue is interpreted as a good signal and reduces the refinancing costs of the sponsoring bank. If banks’ leverage is high or the negative shock is sizable enough, the equilibrium is a pooling one in which all banks rescue. When the aggregate financial sector is close to insolvency, banks’ expected net worth would increase if rescues were banned. The model can be extended to discuss the circumstances in which all banks collapse after rescuing their vehicles.

    Financial frictions, product quality, and international trade

    Abstract

    Product quality plays a key role in economics, but differs markedly across countries and industries. What are the determinants and implications of this pattern? In this paper, we test an explanation for the large heterogeneity in product quality that rests on the interplay between cross-country differences in financial frictions and cross-industry differences in financial vulnerability. To guide the empirical analysis, we rely on a simple trade model featuring heterogeneous firms, endogenous output quality, country heterogeneity in financial frictions, and industry heterogeneity in financial vulnerability. The model clearly illustrates how the interaction of financial frictions and financial vulnerability shapes the geographical and sectoral variation in product quality. We estimate the model using a novel data set, which contains proxies for export quality, financial development, and financial vulnerability for virtually all manufacturing industries and countries in the world, over a period that spans the last three decades. Our results show that the interplay between financial frictions and financial vulnerability is a main driver of the observed variation in product quality across countries and industries. The model also suggests that quality adjustments are an important mechanism through which financial development affects international trade and shapes countries’ export structure. We find strong evidence consistent with this implication.

    Educate to Lead? The Local Political Economy Effects of School Construction in Indonesia

    Abstract

    The extension of mass education not only affects the level of education of the labor force, but also raises the average education of local politicians. This paper investigates the impact of a large program of school construction in Indonesia on local governance and public good provision. By using a panel dataset of 10,000 villages and exploiting the staggered timing of local elections, I isolate the effects driven by changes in local governance. The results suggest that the school construction program led to important increases in the provision of public goods. Furthermore, the results are heterogeneous across villages: public goods experienced stronger increases in villages where there was a particular demand for that type of public good. I provide evidence that the results are driven by the increase in the level of education of the village head, which suggests that the level of human capital of local politicians is a key ingredient of public good provision in developing countries.

    The effect of a child on female work when family planning may fail

    Abstract

    This paper develops a structural empirical model of contraception and participation choice under imperfect control of fertility, learning and unobserved heterogeneity to identify, estimate and give a behavioral content to the effect of the first born child on female labor supply. Family planning failures are exploited as sources of identification. The data are drawn from the 1995 US National Survey of Family Growth (NSFG) which no one has used before for this purpose and which contains full retrospective information on participation, contraception and children. The model is estimated combining the Nested Pseudo Likelihood Estimation and the Expected-Maximization algorithm. Key factors driving the importance of the effect are education, labor market experience, child's age and preferences for leisure and children. From a policy perspective, this heterogeneity is important in designing maternity leave and child care policies. Additionally, twins and gender composition of children are used as sources of variation in the model to estimate the effect of the second and the third born child. The Average Treatment Effect (ATE) of the first is -12.4%, of the second is -5.6% and of third born child is -4.9%. Finally, based on the dynamic model a weighting procedure is proposed to understand the Local Average Treatment Effects (LATE) found in the nonstructural literature.

    Neglected serial correlation tests in UCARIMA models

    Abstract

    We derive computationally simple and intuitive score tests of neglected serial correlation in unobserved component univariate models using frequency domain techniques. In some common situations in which the information matrix is singular under the null we derive extremum tests that are asymptotically equivalent to likelihood ratio tests, which become one-sided, and explain how to compute reliable Wald tests. We also explicitly relate the incidence of those problems to the model identification conditions and compare our tests with tests based on the reduced form prediction errors. Our Monte Carlo exercises assess the finite sample reliability and power of our proposed tests.

    Distributional linkages between European sovereign bond and bank asset returns

    Abstract

    We analyse the dependence between sovereign bonds’ and banks’ asset return distributions with a large panel of European data from 2001 to 2013. Using quantile regressions, we identify nonlinear contemporaneous and lagged dependence. As a result, shocks to crisis-hit sovereign bonds have contemporaneous effects on the whole distribution of banks’ returns, as well as a persistent impact in the tails. Our results offer relevant insights about the relationship between banking and sovereign crises. In particular, during the recent financial crisis, banks’ asset return distributions have lower means and fatter tails than in the absence of a simultaneous sovereign crisis.

    Capital regulation in a macroeconomic model with three layers of default

    Abstract

    We develop a dynamic general equilibrium model for the positive and normative analysis of macroprudential policies. Optimizing financial intermediaries allocate their scarce net worth together with funds raised from saving households across two lending activities, mortgage and corporate lending. For all borrowers (households, firms, and banks) external financing takes the form of debt which is subject to default risk. This "3D model" shows the interplay between three interconnected net worth channels that cause financial amplification and the distortions due to deposit insurance. We apply it to the analysis of capital regulation.

    The optimal scope of the royalty base in patent licensing

    Abstract

    There is considerable controversy about the relative merits of the apportionment rule (which results in per-unit royalties) and the entire market value rule (which results in ad-valorem royalties) as ways to determine the scope of the royalty base in licensing negotiations and disputes. This paper analyzes the welfare implication of the two rules abstracting from implementation and practicability considerations. We show that advalorem royalties tend to lead to lower prices, particularly in the context of successive monopolies. They benefit upstream producers but not necessarily hurt downstream producers. When we endogenize the investment decisions, we show that a sufficient condition for ad-valorem royalties to improve social welfare is that enticing more upstream investment is optimal or when multiple innovators contribute complementary technologies. Our findings contribute to explain why most licensing contracts include royalties based on the value of sales.

    Testing a large number of hypotheses in approximate factor models

    Abstract

    We propose a method to test hypotheses in approximate factor models when the number of restrictions under the null hypothesis grows with the sample size. We use a simple test statistic, based on the sums of squared residuals of the restricted and the unrestricted versions of the model, and derive its asymptotic distribution under different assumptions on the covariance structure of the error term. We show how to standardize the test statistic in the presence of both serial and cross-section correlation to obtain a standard normal limiting distribution. We provide estimators for those quantities that are easy to implement. Finally, we illustrate the small sample performance of these testing procedures through Monte Carlo simulations and apply them to reconsider Reis and Watson (2010)'s hypothesis of existence of a pure inflation factor in the US economy.

    A spectral em algorithm for dynamic factor models

    Abstract

    We introduce a frequency domain version of the EM algorithm for general dynamic factor models. We consider both AR and ARMA processes, for which we develop iterative indirect inference procedures analogous to the algorithms in Hannan (1969). Although our proposed procedure allows researchers to estimate such models by maximum likelihood with many series even without good initial values, we recommend switching to a gradient method that uses the EM principle to swiftly compute frequency domain analytical scores near the optimum. We successfully employ our algorithm to construct an index that captures the common movements of US sectoral employment growth rates.
