Tax evasion in new disguise? Examining tax havens' international bank deposits
with Lukas Menkhoff

WP version: DIW discussion paper No. 1711

Abstract

Bank deposits in tax havens potentially hide illegal tax evasion. The October 2016 release of bilateral locational banking statistics permits us to illuminate three open issues in this respect. We find that the intended effect of additional information-exchange-on-request treaties vanishes since about 2010. This also holds for bank deposits from tax havens in non-havens. In contrast, new treaties based on the automatic exchange of information show bite. This suggests that tax evasion changes its disguise: it adapts to established information exchange treaties while tax evaders seem (partly) surprised by, and thus react to, new treaty forms.

Robust political economy correlates of major product and labor market reforms in advanced economies: Evidence from BAMLE for Logit Models
with Romain Duval and Davide Furceri
Journal of Applied Econometrics, 2020, link here.
WP version: IMF working paper No. 101

Abstract

The political economy literature has put forward a multitude of hypotheses regarding the drivers of structural reforms, but few, if any, empirically robust findings have emerged thus far. To make progress, we draw a parallel with model uncertainty in the growth literature and provide a new version of the Bayesian averaging of maximum likelihood estimates (BAMLE) technique tailored to binary logit models. Relying on a new database of major past labor and product market reforms in advanced countries, we test a large set of variables for robust correlation with reform in each area. We find widespread support for the crisis-induces-reform hypothesis. Outside pressure increases the likelihood of reform in certain areas: reforms are more likely when other countries also undertake them and when there is formal pressure to implement them. Other robust correlates are more specific to certain areas — for example, international pressure and political factors are most relevant for product market and job protection reforms, respectively.

Lost in Information: National Implementation of Global Tax Agreements
with Annette Alstadsæter, Elisa Casi-Eberhard, and Barbara Stage
WP version: NHH Discussion Paper No. 2020/1 and Skatteforsk Working Paper No. 10

Abstract

This paper studies how national implementation shapes individual responses to global agreements by looking at the introduction of the multilateral standard for automatic information exchange on financial assets, i.e., the Common Reporting Standard (CRS). We utilize rich micro-level data on all bank transfers to Norway. This provides us with unparalleled detail on hidden ownership structures. These data show a significant increase in cash repatriation from tax havens post-CRS implementation. Yet, we document substantial heterogeneity in responses down to a null result if CRS enforcement is weak. Relying on macroeconomic data on crossborder bank deposits, we employ model averaging techniques to establish the most important characteristics of the receiving countries that make the CRS more effective. Our results suggest that a highly digitized tax administration triggers twice the drop in tax haven deposits compared to a tax administration relying on paper tax returns. These results have implications for global policy initiatives more broadly.

Homes Incorporated: Offshore Ownership of Real Estate in the U.K.
with Niels Johannesen and Daniel Weishaar
WP version: CEPR discussion paper No. DP17738 and CESifo Working Paper No. 10159

Abstract

Ownership of real estate through corporations in offshore tax havens creates opportunities for tax evasion and money laundering and may have undesirable effects in housing markets. In this paper, we study offshore ownership of real estate in the United Kingdom by combining several data sources: administrative data from the land register, a comprehensive transaction database, a propriety database on corporate ownership links, and a handful of offshore data leaks. Our descriptive analysis shows that the market share of offshore corporations has increased over time and varies strongly across market segments: It currently stands at 1.25% in the overall residential market and around 15% for top-end properties. When data leaks allow us to trace ownership through offshore corporations to the beneficial owners, we find that around half have ties to Africa, Asia and the Middle East, but that the largest ‘foreign’ investor is the United Kingdom itself. Turning to causal evidence, we show that changes in tax incentives and ownership transparency induce strong responses in patterns of offshore ownership, suggesting that both taxation and secrecy are important motives for the beneficial owners. Finally, we show that the Brexit referendum was followed by a sharp increase in property sales by offshore owners and a large differential decrease in property prices in local areas with more offshore ownership, conditional on area and property characteristics. This suggests that the reduction in demand from offshore investors triggered by Brexit had a negative causal effect on property prices and, more broadly, that offshore ownership can have significant real effects in housing markets.

The elusive banker. Using hurricanes to uncover (non-) activity in offshore financial centers
WP version: CESifo Working Paper No. 8625

Abstract

This paper studies financial service provision booked through offshore financial centers (OFCs). Based on several novel data sources and recent advances in event study methodology, I exploit the natural experiment of re-occurring hurricanes hitting small islands and compare local reactions to reactions in financial service activity. I find that local conditions, captured by monthly satellite data on nightlight intensity, deteriorate significantly for nine months. However, in OFCs, the international bank sector does not react. Non-OFC islands on the other hand do show strong negative reactions. Similar (non-)reactions are visible in equity prices. Additionally, a link of OFC service provision to activity in London, Tokyo, and New York is visible in leaked data. Finally, a long term relationship between offshore finance and local development is absent, but only on OFCs. These results indicate that international regulation attempts that aim at forcing OCFs to provide information on financial service activity could be targeted better, they show that we mis-allocate financial risk to OFCs, and they cast doubt on offshore finance as a valid development strategy.

The multinational capital advantage (working title)
with Sarah Clifford

Abstract

In this paper we provide evidence of a tangible advantage of being multinational when weathering external shocks. We combine multiple sources of entity level panel data and compare the borrowing and lending patterns of affiliates of multinational enterprises to the patterns of local firms at the onset of a period of bank credit shortage. We first document that multinational affiliates have access to substantially more debt than similar domestic firms after a shock to external credit markets. Second, we show that part of this capital advantage comes from access to the group internal capital market of the multinational. Third, we show that two groups of affiliates in particular drive these differences: the ones that are likely financially constrained when the credit shock hits and the ones that appear especially profitable. We interpret this as MNEs bailing out the members that are in trouble as a result of less access to bank finance as well as supporting especially profitable members to take over larger market shares following bank credit shortage in an area. Lastly, we document that this capital advantage results in a significant performance difference with multinational affiliates growing substantially faster than local firms after the external credit shock. Unlike domestic firms, multinational enterprises have access to a group-internal capital market that spans countries. We show that this internal capital market increases resilience of multinational affiliates during economic downturns. We combine multiple sources of entity level panel data and compare the borrowing and lending patterns of affiliates of multinational enterprises to the patterns of fully domestic firms at the onset of a period of bank credit shortage. We first document that multinational affiliates take on 10-15% more debt than similar domestic firms after a shock to external credit markets. Second, we show that this additional debt is driven by financing coming from within the multinational group i.e. via the internal capital market of the multinational. Third, we show that two groups of affiliates in particular drive these differences: the ones that are likely financially constrained when the credit shock hits and the ones that appear especially profitable. We interpret this as MNEs bailing out the members that are in trouble as a result of less access to bank finance as well as supporting especially profitable members to take over larger market shares following bank credit shortage in an area.

Germany’s Efforts to Curb International Tax Evasion
with Hannes Fauser

Abstract

We evaluate the impact of regulatory attempts by German authorities to combat international tax evasion. Monthly cross-border deposits from tax havens in German banks show a 32-34% reduction in reaction to bilateral information exchange. These findings are comparable in magnitude to a number of reference studies which confirms Germany as a valid case study for international tax evasion. We show disaggregated reactions for a list of tax havens and find large reactions to information exchange for Guernsey, the Bahamas, and Jersey. We then employ a manually constructed narrative databases collecting changes in the German tax code and information leaks from tax havens. Tax evaders do not react to changes in tax rates and leaks show consistent signs but are rarely significant. These results confirm information exchange as the main focus in the analysis of international tax evasion.


Making the invisible visible. An empirical assessment of the Eurodollar and its consequences
with Andrea Binder

Abstract

The repressed recovery from the 2008/2009 Financial Crisis has highlighted significant frictions in the US-dollar based international monetary system. Researchers argue that one reason for this predicament is the Eurodollar, i.e. money creation outside national regulation. Yet, empirical evidence on the Eurodollar system is scant as available statistical data does not distinguish between US dollar and the Eurodollar. This paper asks about the role of the Eurodollar in the international monetary order, both in size and in substance. Building on a conceptual analysis of the distinct nature of the two currencies the paper proceeds in three steps: First, we construct a global estimate of the volume of the offshore created Eurodollar and compare it to the onshore created US dollar. This is possible via a combination of national currency breakdowns and bilateral exposures to offshore financial centres available in the BIS banking data. Second, we assess the effect that the existence and size of the Eurodollar system has on US monetary policy. Finally, we discuss what the findings mean for the nature and governance of the contemporary international monetary system.
