Tax Collection Costs, Tax Evasion and Optimal Interest Rates

In this paper, I investigate to what extent the cross-country variation in nominal interest rates can be explained as being due to governments' optimal response to economic conditions such as tax collection costs, tax evasion and government consumption needs. In particular, I study the effects of costly income taxes in the presence of an informal sector on the solution to a Ramsey problem in a general equilibrium framework. Unlike most of the previous analyses of optimal inflationary finance, the model postulates that conventional taxes carry collection costs whereas fiat money can be printed costlessly. For some countries, I measure tax collection costs, use the tax evasion estimates reported in the literature, and then calculate the optimal interest rate based on the model. Comparison of the actual and optimal interest rates demonstrates that the model can in fact partly explain the observed deviations from the Friedman Rule. I also show that allowing cross-country differences in the elasticity of substitution between formal and informal sectors can increase the model's explanatory power.

Financing Government Expenditures Optimally

In a simple cash-credit model, I study the effects of the combination of costly tax collection and tax evasion on fiscal and monetary policy for optimal resource allocation. Allowing the informal sector to use cash more intensively than the formal sector, I compute the optimal interest and tax rates for eleven OECD countries to finance their exogeneously given government spending. A comparison of the actual and optimal interest rates reveals that tax collection costs and tax evasion together can partly explain the cross-country differences in monetary policy, also rationalizing deviations from the Friedman Rule in the long-run.

Foreign Currency Borrowing by Small Firms

We examine the firm- and country-level determinants of the currency denomination of small business loans. We first model the choice of loan currency in a framework which features a trade-off between lower cost of debt and the risk of firm-level distress costs, and also examines the impact of information asymmetry between banks and firms. When foreign currency funds come at a lower interest rate, all foreign currency earners as well as those local currency earners with high revenues and low distress costs choose foreign currency loans. When the banks have imperfect information on the currency and level of firms revenues, even more local earners switch to foreign currency loans, as they do not bear the full cost of the corresponding credit risk. We then test the implications of our model by using a 2005 survey with responses from 9,655 firms in 26 transition countries. The survey contains details on 3,105 recent bank loans. At the firm level, our findings suggest that firms with foreign currency income and assets are more likely to borrow in a foreign currency. In contrast, firm-level distress costs and financial transparency affect the currency denomination only weakly. At the country level, the interest rate advantages of foreign currency funds and the exchange rate volatility do not explain the foreign currency borrowing in our sample. However, foreign bank presence, weak corporate governance and the absence of capital controls encourage foreign currency borrowing. All in all, we cannot confirm that "carry-trade behavior" is the key driver of foreign currency borrowing by small firms in transition economies. Our results do, however, support the conjecture that banking-sector structures and institutions that aggravate information asymmetries may facilitate foreign currency borrowing.foreign currency borrowing, competition, banking sector, market structure

Who Needs Credit and Who Gets Credit in Eastern Europe?

Based on survey data covering 8,387 firms in 20 countries we compare credit demand and credit supply for firms in Eastern Europe to those for firms in selected Western European countries. We find that, while 30% of firms do not need credit in Eastern Europe, their need for credit is higher than in Western Europe. The firm-level determinants of credit needs in Eastern Europe are quite similar to that in Western Europe: Firms with alternative financings sources, i.e. government-owned, foreign-owned and internally financed firms, are less likely to need credit. Small firms are also less likely to demand credit than larger firms, suggesting that they may have limited investment opportunities. We find that a higher share of firms is discouraged from applying for a loan in Eastern Europe than in Western Europe. Firms in Eastern Europe seem particularly discouraged by high interest rates compared to firms in Western Europe, with collateral conditions and loan application procedures also more discouraging. The higher rate of discouraged firms in Eastern Europe is related to a stronger reluctance of small and financially opaque firms to apply for a loan compared to Western Europe. While many discouraged firms correctly anticipate that their loan applications would be rejected, a large majority of discouraged firms seem to be creditworthy. At the country-level we find that the higher rate of discouraged firms in Eastern Europe is driven more by the presence of foreign banks than by the macroeconomic environment or the lack of creditor protection. We find no evidence that foreign bank presence leads to stricter loan approval decisions. Our findings suggest to policy makers that the low incidence of bank credit among firms in Eastern Europe, compared to Western Europe, is not driven by less need for credit or banks' reluctance to extend loans. The main driver seems to be that many (creditworthy) firms are discouraged from applying for a loan, due to high interest rates, collateral conditions and cumbersome lending procedures. As discouragement is particularly high among small and opaque firms, as well as in countries with a strong presence of foreign banks, it seems that firms perceive lending standards to have become more reliant on "hard information" with the entry of foreign banks. However, as loan rejection rates are not related to foreign bank presence, it seems that firms' perceptions of the likely lending conditions may be too pessimistic. Thus more transparency about credit eligibility and conditions may improve credit access, particularly in countries with a high presence of foreign banks.Banking, Credit, Transition economies

The recent behaviour of financial market volatility

A striking feature of financial market behaviour in recent years has been the low level of price volatility over a wide range of financial assets and markets. The issue has attracted the attention of central bankers and financial regulators due to the potential implications for financial stability. This paper makes an effort to shed light on this phenomenon, drawing on literature surveys, reviews of previous analyses by non-academic commentators and institutions, and some new empirical evidence. The paper consists of seven sections. Section 2 documents the current low level of volatility, putting it into a historical perspective. Section 3 briefly reviews the theoretical determinants of volatility, with the aim of helping the reader through the subsequent sections of this Report, which are devoted to the explanations of the phenomenon under study. These explanations have been grouped into four categories: real factors; financial factors; shocks; and monetary policy. Thus, Section 4 looks into the relation between volatility and real factors, from both a macro- and a microeconomic perspective. Section 5 considers how the recent developments in financial innovation and improvements in risk management techniques might have contributed to the decline in volatility. Section 6 considers the relation between real and financial shocks and volatility. Finally, Section 7 explores whether more systematic and transparent monetary policies might have led to lower asset price volatility.financial volatility, risk taking, international financial markets

Foreign currency borrowing by small firms in the transition economies

We examine the firm- and country-level determinants of foreign currency borrowing by small firms, using information on the most recent loan extended to 3101 firms in 25 transition countries between 2002 and 2005. Our results suggest that foreign currency borrowing is much stronger related to firm-level foreign currency revenues than it is to country-level interest rate differentials. Supporting the conclusion that carry-trade behavior is not the key driver of foreign currency borrowing in our sample we find no evidence that firm-level indicators of distress costs or financial transparency affect loan currency denomination. Overall, our findings suggest that retail clients which do take foreign currency loans are better equipped to bear the corresponding currency risks than is commonly thought. Policy makers should therefore take a closer look at the characteristics of borrowers before implementing regulations which are aimed at curbing foreign currency loans.Foreign currency borrowing Competition Banking sector Market structure
