We present a new database on financial fragility for 124 countries over 1998 to 2012. In addition to commercial banks, our database incorporates investment banks and real estate and mortgage banks, which are thought to have played a central role in the recent financial crisis. Furthermore, it also includes cooperative banks, savings banks and Islamic banks, that are often thought to have different risk appetites than do commercial banks. As a result, the total value of financial assets in our database is around 50% higher than that accounted for by commercial banks alone. We provide eight different measures of financial fragility, each focussing on a different aspect of vulnerability in the financial system. Alternative selection rules for our variables distinguish between institutions with different levels of reporting frequency.

We analyse how the financial support for long-term elderly care affects the level of household savings. Using a difference-in-differences estimator, we investigate the 2002 Scottish reform, which introduced free formal personal care for all the elderly aged 65 and above residing in Scotland. Our semiparametric estimation technique allows the policy effects to be flexibly estimated across age groups. We find that the Scottish policy reduced the average household saving by about £7,200. Moreover, the estimated effects are heterogeneous across age groups of the head of household: these effects are particularly strong among those aged between 40 and 60. The largest effect is observed at age 49 with the reduction in the average household saving by £12,764.

Many important games are aggregative allowing for robust comparative statics analysis even when a game does not exhibit strategic complements or substitutes (Acemoglu and Jensen (2013)). This paper establishes such comparative statics results for contests improving upon existing results by (i) allowing payoff functions to be discontinuous at the origin, and (ii) allowing for asymmetric rent-seeking contests and patent races. A leading example where (i) is relevant is the classical Tullock contest (Tullock (1980)). The paper also studies existence and uniqueness of equilibria extending the results of Szidarovszky and Okuguchi (1997) and Cornes and Hartley (2005) to patent races.

This paper studies how voter loss-aversion affects electoral competition in a Downsian setting. Assuming that voters’ reference point is the status quo, we show that loss-aversion has a number of effects. First, there is policy rigidity both parties choose platforms equal to the status quo, regardless of other parameters. Second, that there is a moderation effect when there is policy rigidity, the equilibrium policy outcome is closer to the moderate voters’ ideal point than in the absence of loss-aversion. In a dynamic extension of the model, we consider how parties strategically manipulate the status quo to their advantage, and we find that this increases policy rigidity. Finally, we show that with loss-aversion, incumbents adjust less than challengers to changes in voter preferences. The underlying force is that the status quo works to the advantage of the incumbent. This prediction of asymmetric adjustment is new, and we test it using elections to US state legislatures. The results are as predicted: incumbent parties respond less to shocks in the preferences of the median voter.

Distributional comparative statics is the study of how individual decisions and equilibrium outcomes vary with changes in the distribution of economic parameters (income, wealth, productivity, distortions, information, etc.). This paper develops tools to address such issues. Central to the developments is a new condition called quasi-concave differences which implies concavity of the policy function in optimization problems. The results are used to show how Bayesian equilibria respond to increased individual uncertainty (less precise private signals); and to derive conditions for concavity of policy functions in general stochastic dynamic programming problems. The latter generalizes Carroll and Kimball (1996) to models with borrowing constraints in the spirit of Aiyagari (1994).

We quantify the linkages among banks’ equity performance and indicators of sovereign stress by using panel GMM to estimate a three-equation system that examines the impact of sovereign stress, as reflected in both sovereign spreads and sovereign ratings, on bank share prices. We use data for a panel of five euro-area stressed countries. Our findings indicate that a long-run recursive relationship between sovereigns and banks operated during the euro-area crisis. Specifically, for the five crisis countries considered shocks to sovereign spreads fed-through to sovereign ratings, which affected commercial banks’ equity-prices. Our results also point to the importance of using levels of equity prices -- rather than rates of return -- in measuring banks’ performance. The use of levels allows us to derive the determinants of long-run equity prices.

In empirical demand, industrial organization, and labor economics, prices are often unobserved or unobservable since they may only be recorded when an agent transacts. In the absence of any additional information, this partial observability of prices is known to lead to a number of identification problems. However, in this paper, we show that theory-consistent demand analysis remains feasible in the presence of partially observed prices, and hence partially observed implied budget sets, even if we are agnostic about the nature of the missing prices. Our revealed preference approach is empirically meaningful and easy to implement. We illustrate using simple examples.

We study the political determination of the proportion of students attending university when access to higher education is rationed by admission tests. Parents differ in income and in the ability of their unique child. They vote over the minimum ability level required to attend public universities, which are tuition-free and financed by proportional income taxation. University graduates become high skilled, while the other children attend vocational school and become low skilled. Even though individual preferences are neither single-peaked nor single-crossing, we obtain a unique majority voting equilibrium, which can be either classical (with 50% of the population attending university) or ends-against-the-middle with less than 50% attending university (and parents of low and high ability children favoring a smaller university system). The majority chosen university size is smaller than the Pareto efficient level in an ends-against-the-middle equilibrium. Higher income inequality decreases the majority chosen size of the university. A larger positive correlation between parents’ income and child’s ability leads to a larger university populated by a larger fraction of rich students, in line with the so-called participation gap. Our results are robust to the introduction of private schooling alternatives, financed with fees.

I study the effects of tax evasion on economic growth by focusing on the cultural aspects of tax compliance and their effect on the extensive margin of tax evasion. A cultural norm that determines the contemptibility of tax dodging practices links the past incidence of tax evasion with the tax payers’ current incentives to conceal sources of income. This dynamic complementarity may lead to multiple equilibria in the evolution of tax evasion. Due to the latter’s effect on capital accumulation, this multiplicity may lead economies in divergent development paths, as long as they differ in the initial magnitude of tax evasion. This happens even though economies may be, on the outset, identical in terms of capital stock and structural characteristics, including those that govern tax enforcement.

Empirical evaluation of macroeconomic uncertainty and its use for probabilistic forecasting are investigated. New indicators of forecast uncertainty, which either include or exclude effects of macroeconomic policy, are developed. These indicators are derived from the weighted skew normal distribution proposed in this paper, which parameters are interpretable in relation to monetary policy outcomes and actions. This distribution is fitted to forecast errors, obtained recursively, of annual inflation recorded monthly for 38 countries. Forecast uncertainty term structure is evaluated for U.K. and U.S. using new indicators and compared with earlier results. This paper has supplementary material.
