This chapter draws on our two studies published by the International Centre for Tax and Development (ICTD), using the two leading datasets on the global activity of multinational enterprises (MNEs). The approaches are complementary but necessarily distinct, given the difference in available data. We summarise the approaches taken, and the specific findings that emerge from each, and then highlight three major common results. First, notwithstanding uncertainty and data issues, this is a first-order problem in relation to the world economy. Second, the overall effect of a switch to unitary taxation, almost regardless of the actual apportionment formulas used, would be a substantial redistribution from MNEs towards most countries of the world. Only a handful of jurisdictions would see significant revenue losses, and these are far outweighed by the gains of all others. Third, there are significant differences in the extent of redistribution implied by a global apportionment approach relying on different factors – with corresponding implications for the development impact of given global choices, and/or for unilateral decisions at regional and national level. Overall, the findings confirm the critical importance of improving the available data. In doing so, they underline the failure of the OECD base erosion and profit shifting (BEPS) process to deliver on commitments in this area, but also highlight the potential of using the newly-required country-by-country reporting data of MNEs. A specific proposal for a data registry is put forward.

Hendrik Jungmann , Simon Loretz, On the measurement of investment types: Heterogeneity in corporate tax elasticities
University of Salzburg Working Papers in Economics and Finance, 2016, (1), 37 pages, https://www.uni-salzburg.at/fileadmin/multimedia/SOWI/documents/working_papers/WorkingPaper_2016_01.pdf
This paper highlights the importance of different investment motives and to what extend they affect the responsiveness to corporate taxation. In particular, we discuss how to classify investment as non-related, horizontal, vertical and complex types using a combination of both firm-specific (ownership) information and sector-specific information from input-output tables. Hereby, we point out to what extent the resulting classification depends on assumptions made by the researcher. Following this, we examine the effects of host-country corporate taxation on the volume of investment within related firms (i.e., the intensive margin). We are able to quantitatively replicate the average result in the empirical literature with an overall tax semi-elasticity of approximately –1.5. Taking into account firm-heterogeneity we find that non-related investments react stronger to corporate taxation whereas horizontal investments are less responsive, though, significant negative tax semi-elasticities turn out for the subset of manufacturing industries where horizontal investment is much more prevalent. As the strict categorical classification still yields ambiguous results for both vertical and complex investments we extend the methodology by defining shares of investment and make the point that, by and large, stronger business motives reduce the tax responsiveness of investment.

During the last decade the beer market has been in the focus of the media, largely because of spectacular mergers among the big players. The formation of Anheuser-Busch InBev created the world's largest brewing company with a global market share of approximately 20 percent. This consolidation process in the beer market triggered substantial interest as to how concentrated the market will eventually become and its key driving forces.

Simon Loretz, Socrates Mokkas, Evidence for Profit Shifting with Tax-sensitive Capital Stocks
Public Finance Analysis, 2015, (1), 36 pages, pp.1-36, http://www.ingentaconnect.com/content/mohr/fa/2015/00000071/00000001/art00001
This paper contributes to the literature providing indirect evidence for profit shifting within multinational companies. In contrast to the previous studies, we take account of the tax responsiveness of the capital stock and analyse the effect of corporate taxes on both pre- and post-tax profitability. Evidence from a system of equations using a large panel data set of European subsidiaries by and large supports the profit-shifting hypothesis. We find that a 10-percentage-point decrease in the tax rate increases post-tax profitability by up to 0.6 percentage point, with a larger direct tax effect. Further, our results suggest that financial profits and losses are particularly responsive to taxes, which indicates that a large part of profit shifting takes place via debt shifting.

Die Situation des österreichischen Föderalismus ist geprägt durch ein starkes vertikales fiskalisches Ungleichgewicht, vor allem die Länder haben kaum Autonomie über die Einnahmen. Diese Diskrepanz ist u. a. auf eine Angst vor ruinösem Steuerwettbewerb zurückzuführen, führt aber gleichzeitig zu einem Mangel an Transparenz und verändert Anreize für die lokalen Entscheidungsträger. Eine Umwandlung der Ertragsanteile von Lohn- und Einkommensteuer und Körperschaftsteuer in teilweise Steuerautonomie der Bundesländer würde wesentlich zur Transparenz beitragen und könnte durch einsetzenden Steuerwettbewerb auch die Anreize für effiziente lokale Verwaltung verbessern. Erfahrungen aus anderen föderalen Staaten zeigen auch, dass Steuerwettbewerb ein wesentlicher Bestandteil des fiskalischen Föderalismus ist und dass die Rahmenbedingungen wie klare Aufgabentrennung zwischen den Gebietskörperschaften und ein entsprechend ausgestalteter horizontaler Finanzausgleich den fiskalischen Wettbewerb in gesunde Bahnen lenken können.

This survey summarises the state and development of European tax policy, in particular discussing the harmonisation progress in direct as well as indirect taxes. Based on an overview over the theoretical and empirical literature on tax competition, we further ask whether increased tax coordination is necessary to prevent a race to the bottom. We show that theoretical predictions on the outcome of tax competition are ambiguous, and the empirical evidence in this regard is inconclusive as well. This, in turn, gives rise to an only limited scope of stronger tax harmonisation.

Michael P. Devereux, Li Liu, Simon Loretz, The Elasticity of Corporate Taxable Income: New Evidence from UK Tax Records
American Economic Journal: Economic Policy, 2014, (2), pp.19-53, https://econpapers.repec.org/article/aeaaejpol/v_3a6_3ay_3a2014_3ai_3a2_3ap_3a19-53.htm
We estimate the elasticity of corporate taxable income with respect to the statutory corporation tax rate using the population of UK corporation tax returns. We analyse bunching in the distribution of taxable income at kinks in the marginal rate schedule. We decompose this elasticity into an elasticity of total income with respect to the corporation tax rate, and an elasticity of the share of income taken as profit with respect to the difference between the personal and corporate tax rates. This implies a marginal deadweight cost at the 10,000 £ kink of around 29 percent of tax revenue.

Over the last couple of years the beer industry has experienced an intense consolidation process resulting in an every declining number of globally active brewing companies. At the same time, in some large beer markets the number of micro-breweries steadily increased. While the former is often explained by prevailing economies of scale in this industry the latter is often associated with demand side arguments including love-of-variety preferences. This chapter offers an additional explanation for these tendencies observed in the beer markets. More precisely, we argue that a country's policy concerning the taxation of beer products might have a direct impact on the emerging market structure. More precisely, our main finding supports the view that EU's beer excise tax regulation which couples a minimum amount of beer excise taxes obliged to charge with the possibility of reduced rates for small breweries has direct implications for the market structure in the brewing industry. More precisely, this regulation tends to trigger a polarisation of the market in the sense that one observes a very small number of large and globally active brewing companies while, at the same time, the number of micro-breweries increases. Medium-sized beer producers tend to be forced out of the market by this regulation or choose to adjust their production level to a smaller amount. Some of the (formerly) medium-scale beer producers also have been targets of mergers and acquisitions,which further fosters an increase in market concentration among the global players in beer producing. This overall finding confirms that specific tax rules might directly and indirectly affect market structures and in the medium-run might also have implications for customers. Especially, the very small number of globally active brewing companies might increase the likelihood for collusive behaviour and thus calls for a careful monitoring by competition authorities all over the world.
