Measuring Income Tax Evasion using Bank Credit: Evidence from Greece
with Nikolaos Artavanis and Adair Morse , Forthcoming Quarterly Journal of Economics
Winner of the Wharton School-WRDS Award for the Best Empirical Finance Paper, WFA 2013
Abstract: We show that in semiformal economies, banks lend to tax-evading individuals based on the bank's perception of the individual's true income. This observation leads to a novel approach to estimate tax evasion using the adaptation of the private sector to the norms of semiformality. We use bank microdata on household credit, and replicate the bank model of credit capacity decision to infer the bank’s estimate of individuals’ true income. We estimate a lower bound of 28.2 billion euros of unreported income for Greece. The foregone government revenues amount to 32% of the deficit for 2009. Primary tax-evading industries are medicine, law, engineering, education, and media. We provide evidence that tax evasion persists not because the tax authorities are unaware, but because of a lack of paper trail and political willpower. Finally, we speak to the reproducibility and applicability of our method in other semiformal settings.

Abstract:This paper provides causal evidence on the impact of succession taxes on firm investment decisions and transfer of control. I exploit a 2002 policy change in Greece that substantially reduced the tax on intra-family transfers of businesses and show that succession taxes lead to more than a 40% decline in investment around family successions, slow sales growth, and depletion of cash reserves. Furthermore, succession taxes strongly affect the decision to sell or retain the firm within the family. I conclude by discussing implications of my findings for firms in the United States and Europe.
Shareholder Democracy in Play: Career Consequences of Proxy Contests
with Vyacheslav Fos
Journal of Financial Economics 114 (2014), pp. 316-340
Abstract:This paper shows that proxy contests have a significant adverse effect on careers of incumbent directors. Following a proxy contest, directors experience a significant decline in number of directorships not only in the targeted company, but also in other non-targeted companies. The results are established using the universe of all proxy contests during 1996-2010. To establish that this effect of proxy contests is causal, we use within-firm variation in directors' exposure to proxy contests and exploit the predetermined schedule of staggered boards that only allows a fraction of directors to be nominated for election every year. We find that nominated directors relative to non-nominated ones lose 45% more seats on other boards. We discuss that this pattern can be expected if proxy contest mechanism imposes a significant career cost on incumbent directors.

Abstract: Using a hand-collected sample of more than 30,000 directors nominated for election over the period 2001–2010, we construct a novel measure of director proximity to elections—Closeness-to-election. We find that the closer a director is to her next election, the higher is CEO turnover–performance sensitivity. Each year closer to director elections is associated with a 23% increase in CEO turnover–performance sensitivity. Three tests support a causal interpretation of the results. First, when we require directors to have a minimum tenure of three years, there is no material change in the results, suggesting that the timing of when directors join their boards is unlikely to drive the results. Second, we find similar results when we use director Closeness-to-election on other boards as a measure of proximity to elections. Third, when we restrict the analysis to firms with unitary boards, there is no material change in the results, suggesting that director self-selection into firms with staggered boards does not drive the results. Cross-sectional tests suggest that, when other governance mechanisms are in place, CEO turnover–performance sensitivity is affected to a lesser extent by Closeness-to-election. We conclude that director elections have important implications for corporate governance.

Abstract: The purpose of the paper is to examine the effect of founding family control on the cost of bank debt. We examine the cost of accessing the syndicated market and we use the financial crisis and the unexpected nature of Lehman Brother's collapse as a laboratory in order to tease out the effect of family ownership. We find that the increase in loan spreads around the Lehman crisis was by at least 24 basis points lower for family firms. Furthermore, the gap in spreads among family and non-family firms becomes wider among firms that had pre-crisis relationships with lenders with higher exposure to the shock. The evidence are consistent with family ownership lowering the cost of accessing debt financing especially when lenders are constrained. We further investigate potential channels that drive the effect of family ownership. We provide novel evidence that for 17% of the family firms creditors impose explicit restrictions in private credit agreements that require the founding family to maintain a minimum percentage of ownership or voting power. Thus creditors value the presence of the family. Furthermore, the impact of family control on lowering the cost of bank debt is higher when family CEOs run the firms and among firms with higher ex ante agency conflicts.
Financial Development and the Credit Cycle in Greece
with Michael Haliassos, Gikas Hardouvelis and Dimitri Vayanos
(2015) Prepared for an MIT Press volume on reforms in Greece, edited by Meghir, Pissarides, Vayanos, and Vettas
Abstract: We review the developments in Greece’s financial system since the beginning of the crisis. We also place them in a broader context by (i) evaluating the long-term performance of Greece’s financial system in comparison to other countries, and (ii) reviewing the credit boom-and-bust cycle that Greece has experienced since Euro entry. Risks in the Greek economy remain overly concentrated to those originating them and are not well diversified. By raising the cost of equity capital for firms, this impedes investment. It also drives up corporate leverage, thus making the economy more vulnerable to shocks. These vulnerabilities manifested themselves even before the sovereign crisis hit. Strengthening investor protection, through improvements in the justice system and financial regulation, is an important part of the solution. In the shorter run, the debt overhang problem in the private sector should be addressed. We discuss policy options to achieve these goals.
