The effects of placer mining on the environment in Central Alaska

Within the Tolovana Mining District, as a result of placer mining, 800 acres of land have been disturbed (0.25% of the land area) and 4 million cubic yards of much have been transported down the Tolovana River through the subsiding Minto Flats. This has increased the rate of sedimentation of the lakes adjacent to the Tolovana River. Mine tailings are about 50% revegetated by natural species. Approximately 60 million cubic yards of muck must be removed to mine the Livengood deposits. A large area of settling ponds will be needed if the deposit is stripped by hydraulic means, or a large area for stacking overburden if mechanical stripping is required. The Crooked Creek area, mined for 80 years has 1,900 acres disturbed (0.7% of the land area) and 200,000 cubic yards of much has been stripped. No correlation is apparent between mining and the non-anadromous fish population, although sport fishing is considered by some to be not as good as a result of mining. Portions of the stream system observed to be impacted with mud showed evidence of having been periodically flushed out. Slave analysis and trace element analysis were applied in an attempt to trace sediments back to their sources, but were not successful. Mining is the pioneer industry around which much of the State of Alaska developed. The transportation network required by the mining industry benefits sportsmen, the tour industry, and directly increases the value of adjacent land. The profit from mining brought much of the early population to the state, and will be a steady source of revenue in years to come

The Euro area's macroeconomic balancing act

The European Systemic Risk Board (ESRB) and the proposed prevention and correction of macroeconomic imbalances regulation (EIP) are designed to avoid imbalances. However, these instruments overlap, and need clarification. Both the ESRB and the Commission, which is given certain powers by the EIP, must identify and act early on risks. Acting in the face of strong economic and political pressure is difficult. Complementing the current approach with transparent and rules-based mechanisms will reduce this problem. The EIP and ESRB can complement each other in terms of analysis and policy, and close collaboration will be vital. The EIP regulation can be used to ensure that ESRB recommendations are followed up. In the area of financial recommendations relevent to macroeconomic imbalances, the Commission should have a more formal requirement to act on ESRB recommendations. The EIP regulation would benefit from a clause allowing recommendations to be addressed not only to member states. Conflicts between the ESRB and Commission could arise. In this case, the Treaty requires the Commission to issue a recommendation even if the ESRB issues a negative finding. Legally, it might not be possible to exclude the use by the Commission of confidential information obtained in the ESRB.

Fiscal crises in US cities: Structural and non-structural causes

Financial difficulties of U.S. cities have recently become a major issue of concern. However, there is little agreement on why certain cities experience crises while others do not. Two arguments are put forward: Cities suffer from (1) structural problems like high immigration, congestion etc. (2) nonstructural political problems like the weakness of the mayor, union-power etc. Starting from a common pool model of municipal goods we estimate demand equations for spending and debt with structural variables. The estimation is based on 900 US cities in 1985, 1991 and 1999. Structural factors predicted by the model explain most of the variation of spending and debt levels. Furthermore coefficients are stable over time. However, excessively high debt burdens as indicators of potential crisis, and high spending levels are outliers and not explained by structural factors. --

Challenges for the euro area and implications for Latvia

This Policy Contribution reviews the major challenges faced by the euro area, and discusses recent initiatives and the way forward. Some implications are drawn out for Latviaâ??s euro accession, which is likely to be beneficial on balance. The euro area faces three major challenges: (1) high private and public debt in some of its parts together with a requirement for competitiveness adjustment that in some countries has barely started; (2) weak growth outlook; (3) continued banking-sector fragility that, with sovereign stress, feeds a negative feedback loop. The euro area has agreed many significant measures to overcome these problems, including the European Stability Mechanism and the fiscal compact. The 21 February agreement on Greece removes a major source of financial instability even though it is likely that further debt reductions will be needed. Significant concerns remain, the most important of which are the slow real economic adjustment and the largely unaddressed banking-sovereign fragility. The fiscal compact raises the issue of appropriate fiscal stabilisation tools at the euro-area level. Countries that will soon join the euro should actively shape the debate about the further development of the overall set-up. For Latvia, joining the euro makes sense because Latvia has kept its exchange rate fixed and has undergone internal adjustment. In its euro-area accession negotiations, Latvia should ensure that it does not participate in any of the currently ongoing financial assistance programmes. This Policy Contribution reproduces evidence given by Guntram B. Wolff to the Latvian parliamentâ??s European affairs committee, 22 February 2012.

Is recent bank stress really driven by the sovereign debt crisis?

Stress in the interbank market has increased dramatically since July and bank stock market valuation has fallen by 22 percent on average for 60 of the most important banks tested in the EBA stress tests. I find evidence that bank stock valuation is significantly and economically meaningfully affected by the bankâ??s exposure to Greek debt. Greek banks are particularly affected. Holdings of debt of the other four periphery countries does not however appear to be a strong determinant of stock price movements. Policy announcements of 21 July of no haircut on any sovereign but Greece appear to be perceived as credible. The exposure to Greece cannot explain the general and large decline in euro area banksâ?? market cap. Instead, a general confidence crisis of the euro area banking system, or more deeply the euro area construction, might be driving the fall in stock prices. The summit of 23 October should focus on restoring confidence in euro-area policymakersâ?? ability and determination to put the euro area on a sound footing. Recapitalisation of banks can only be only one aspect. A credible solution to Greece and a way forward for the larger institutional set-up, including a federal fiscal back-stop of the banking system, are of at least equal importance.

Measuring tax burdens in Europe

This paper calculates effective macro-economic tax rates for the 25 EU countries following the methodology developed in Mendoza, Razin, and Tesar (1994). The available Eurostat data allow to compute the tax wedge on consumption, labor and capital. We show that effective tax rates in the 10 new member states of the EU are on average 10 percentage points lower on labor, and 5 percentage points lower on capital and consumption. There is no tendency of convergence in effective tax burdens on capital. The newly computed tax rates are in line with the effective tax rates of the EU Commission for EU 15. Effective tax rates on capital are only weakly connected to statutory tax rates on corporate income. As they are calculated from macroeconomic data they provide only limited information on the actual tax burdens of individual corporations or households. --Effective tax,Europe

Should non-euro area countries join the single supervisory mechanism?

Irrespective of the euro crisis, a European banking union makes sense, including for non-euro area countries, because of the extent of European Union financial integration. The Single Supervisory Mechanism (SSM) is the first element of the banking union. From the point of view of non-euro countries, the draft SSM regulation as amended by the EU Council includes strong safeguards relating to decision-making, accountability, attention to financial stability in small countries and the applicability of national macroprudential measures. Non-euro countries will also have the right to leave the SSM and thereby exempt themselves from a supervisory decision. The SSM by itself cannot bring the full benefits of the banking union, but would foster financial integration, improve the supervision of cross-border banks, ensure greater consistency of supervisory practices, increase the quality of supervision, avoid competitive distortions and provide ample supervisory information. While the decision to join the SSM is made difficult by uncertainty surrounding other elements of the banking union, including possible burden sharing, we conclude that non-euro EU members should stand ready to join the SSM and be prepared for negotiations on the other elements of the banking union

Fool the markets? Creative accounting, fiscal transparency and sovereign risk premia

We investigate the effects of official fiscal data and creative accounting signals on interest rate spreads between bond yields in the European Union. Our model predicts that risk premia contained in government bond spreads should increase in both, the official fiscal position and the expected "creative" part of fiscal policy. The relative importance of these two signals depends on the transparency of the country. Greater transparency reduces risk premia. The empirical results confirm the hypotheses. Creative accounting increases the spread. The increase of the risk premium is stronger if financial markets are unsure about the true extent of creative accounting. Fiscal transparency reduces risk premia. Instrumental variable regressions confirm these results by addressing potential reverse causality problems and measurement bias. --Risk premia,government bond yields,creative accounting,stock-flow adjustments,gimmickry,transparency

Sovereign bond market integration: the euro, trading platforms and globalization

We disentangle different driving factors of sovereign bond market integration by studying yield co-movements of EMU countries, the UK, the US and 16 German Länder in the last 15 years. At a low frequency of weeks, bond market integration has increased gradually in the course of the last 15 years in EMU countries, as well as the UK, the US and the German Länder. The euro, as well as increasing international capital flows, appear to drive low frequency integration. In contrast, yield adjustments to changes of the German benchmark bond at high frequencies, i.e., 2 days, remain relatively low until October 2000, when a sharp increase in integration can be observed in all samples. The increase in high frequency integration can be attributed to electronic trading platforms becoming functional. The change-over from national currencies to the euro can not explain the dramatic increase in high frequency integration. --sovereign bond market,bond market integration,EMU,electronic trading
