Construction and Assessment of a Mixed Exchange Policy Indicator: Explanation of Polish Inflation
The impact of exchange policy on macroeconomic targets (growth, inflationâŠ) is rather difficult to assess empirically. There is a lack of accurate quantitative tools to define the strategy used, then a dummy variable (fixed or floating rate) is generally used in econometric studies. This paper tries to provide an indicator to measure the trade-off between nominal anchor and real target strategies in open economies. Unlike traditional dummies, it allows a mixed strategy (generally observed) in the managing of the exchange rate, according to external and internal constraints. The analysis of Poland's exchange policy since 1990 shows this trade-off, since monetary authorities have softened their nominal anchor policy to avoid excessive real appreciation. An econometric estimation of Polish inflation is used to test the validity of the indicator suggested. The results confirm not only the classical determinants of inflation, but also the validity of our mixed exchange policy indicator.Indicator, Exchange policy, Poland
Commodity price volatility and Tax revenues: Evidence from developing countries
The recent boom and bust in commodity prices has renewed the policymakersâ interest in three complementary issues: i) characteristics and determinants of commodity price instability, ii) its macroeconomic effects and, iii) the optimal policy responses to this instability. This work falls within the scope of studies dedicated to the macroeconomic effects of commodity price instability, but focuses on the impact on public finance, while existing works were concentrated on growth. This paper also differs from the few previous studies on two aspects. First, we test the impact of commodity price volatility rather than focusing only on price levels. Second, we use disaggregated data on tax revenues (income tax, consumption tax and international trade tax) and on commodity prices (agricultural products, minerals and energy) in order to identify transmission channels between world prices and public finance variables. Our empirical analysis is carried out on 90 developing countries over 1980-2008. We compute an index which measures the volatility of the international price of 41 commodities in the sectors of agriculture, minerals and energy. We find robust evidence that tax revenues in developing countries increase with the rise of commodity prices but that they are hurt by the volatility of these prices. More specifically, price short-run volatility of imported commodities hurts tax revenues through trade and consumption taxes, while price medium-run volatility of export hurts tax revenues through both indirect and direct taxes. These findings point at the detrimental effect of commodity price volatility on developing countries public finances and highlight further the importance of finding ways to limit this price volatility and to implement policy measures to mitigate its adverse effects.Price Volatility, Primary Commodities, Tax Revenues, Developing economies.
Deflation in China
This article investigates the causes of the deflation which occurs in China since 1998. The analysis is based on a theoretical model which addresses supply shocks as well as demand shocks and on the estimation of a reduced equation of consumer prices variations for the period 1986-2002, the results of which corroborate the theoretical assumptions. The main conclusion is that the slowing down of inflation and the fall of prices are chiefly explained by China economic policy. Moreover and contrary to the current opinion we show that deflation is partly due to the deceleration of productivity growth.productivity growth, exchange rate anchorage, deflation, China
Can domestic debt contribute to the financing of the âMillennium Development Goalsâ ? The case of the West African Economic and Monetary Union (WAEMU)
Developing countries are being urged to extent public spending to reach The Millennium Development Goals (MDGs). Following a series of debt cancellations, the public debt of many developing countries has reached low levels, so that external borrowing is a plausible option. However, developing countries can not exclusively rely on external financing. Consequently, is an increase in the domestic debt possible and desirable? This paper investigates this issue in the case of the West African Economic and Monetary Union (WAEMU), of which several countries have benefited from important debt cancellations. We show that an increase in the domestic debt is feasible for some of the WAEMU countries since 1) there exist excess bank liquidity and foreign reserves which involve a low cost for public finance, 2) the main macroeconomic risks (debt distress, crowding out of private investment and real exchange rate appreciation) can be averted and 3) absorptive capacity may be enlarged by giving larger role to regional institutions or local communities.

Deforestation and credit cycles in Latin American countries
This paper establishes a link between deforestation and credit cycles in Latin American countries. The latter exhibit rapid deforestation rates as well as macroeconomic instability that is often rooted in credit booms and crunches episodes: data available on the last years show a coincidence between higher macroeconomic instability and deforestation increases. This paper provides a theoretical explanation and econometric investigations of this phenomenon. A key ingredient of the model is the existence of two sectors: a modern agricultural sector and a subsistence one, which are hypothesised to catch the basic features of Latin American agricultural sectors. Agricultural production relies on three production factors: land, capital and labour. Agents clear forested areas in order to increase agricultural lands. Interest rates movements have an effect on agricultural decisions and thus on deforestation since they induce factor movements between the agricultural sectors. It is shown that deforestation occurs in response to interest rates increases or decreases primarily because of the irreversible character of forest conversion. Econometric tests are conducted on the 1948-2005 period on an exhaustive sample of Latin American countries. The database on deforestation is a compilation of FAO censuses and several measures of credit cycles are calculated as well. The main output of the paper is to evidence a link between credit cycles and deforestation. The results are robust to the introduction of usual control variables in deforestation equations.Credit cycles;deforestation;Latin America

Mofication of Chinese Exchange rate policy: Rationale, extent and recent development
On July 21, China slightly revalued the Renminbi and officially modified the exchange rate regime. Interpreting this move as only the outcome of international pressures to reduce international trade imbalances is however misleading. To support our argument, we explore the rationale of the July 21 decision in the history of exchange rate management in China, and through the review of the twin debates of exchange rate level / regime. We argue that both external and internal concerns are took into account by Chine authorities in the exchange rate management. Moreover, the entire responsibility of Chinese exchange rate management in the world trade imbalances is doubtful. The review of the recent development since the July 21 shows that the impact of July 21 decision is limited. While the hot money inflows seems to have been tamed, the previous economic trends have not been modified to date.China, exchange rate policy, Trade imbalances
The impact of high and volatile commodity prices on public finances: Evidence from developing countries
The recent boom and bust in commodity prices has renewed the policymakers' interest in three complementary issues: i) characteristics and determinants of commodity price instability, ii) its macroeconomic effects and, iii) the optimal policy responses to this instability. This work falls within the scope of studies dedicated to the macroeconomic effects of commodity price instability, but focuses on the impact on public finance, while existing works were concentrated on growth.

We compute an index which measures the volatility of the international price of 41 commodities in the sectors of agriculture, minerals and energy. We find robust evidence that tax revenues in developing countries increase with the rise of commodity prices but that they are hurt by the volatility of these prices. More specifically, increased prices on imported commodities, lead to increased trade taxes and (to a smaller extent) consumption taxes being collected. Export prices are also positively associated with tax revenue collection but the channel is through income taxes and non-tax revenues rather than international trade taxes and consumption taxes. However, the volatility of commodity prices, both of imported and exported commodities, is robustly negatively affecting tax revenues. These findings point at the detrimental effect of commodity price volatility on developing countries public finances and highlight further the importance of finding ways to limit this price volatility and to implement policy measures to mitigate its adverse effects.Price Volatility;Public Finance;Primary Commodities
