Standard and Poor¡¦s (S & P), a global leading corporation in providing credit rating, published the sovereign rating outlook of Taiwan which was ¡§negative sign¡¨ at the end of 2007. The main reason was that the situation of public finance continued worsening. Based on traditional economic theory, the increased deficits or debts led to higher interest rates, and the increasing burden on enterprises for paying more loan cost, would have more adverse effects on the domestic investment activities. Therefore, this study is intended to explore the relationships among the long-term interest rates of public bonds, the outstanding debts, fiscal deficits, and government expenditure in Taiwan by analyzing 53 seasonal data from 1994:4 to 2007:4 as the samples. The findings indicate that no structure breaking points exist in every variable by using CUSUM test, and almost every variable is integrated of order one in unit root test. The results also reveal that there is no long-term relationship among the deficits, government expenditure, and interest rates using the cointegration analysis. There are probably two reasons for explanation: one is that people will increase saving automatically, and another is that the increased interest rates in the tax cut may be offset by the decreased interest rates in debts financing. Moreover, the outstanding debts and interest rates exist a significant negative relationship of long-term equivalence, and further variance decomposition shows that the effect of debts on interest rates is higher than the effect of interest rates on debts in the variable¡¦s explanatory ability. To explain the significant negative relationship, the possible main causes are liquidity factor, and the psychological anticipation of saving in public bond form directly or indirectly; the secondary cause is the fluctuation of interest rates affects the willingness of government financing.

Chronic imbalance between government revenues and expenditures was the main cause of growing public debt in many economies. In economic theory we can find some other arguments that justify deficit financing of government expenditures or public debt. We can mention these arguments -- in some situations (for example natural disaster) government borrowing from other subjects is very prompt and operative way how to gain additional money and seems to be better than other ways (for example better than increase of taxation), government bonds and securities can be very attractive instrument where economic subjects allocate savings and improve liquidity of secondary markets or can be used for monetary policy. On the other hand many arguments against budget deficit and public debt are in theory described and analyzed -- negative affects in savings allocation (crowding-out affect), cost of debt service limits active fiscal policy, debt burden is shifted to other generations, government expenditures from debt financing can negatively effect macroeconomic stability. In theory and in practical policy is public debt and its effects on economy relatively complicated and controversial topic and we can analyze its from economic, technical and political point of view. It results also from the fact that there are many different debt instruments which can be used to finance the budget deficit. A main distinction is the currency of denomination, and, in particular, whether or not is the domestic currency. Another important characteristics is the initial term to maturity, which among marketable instrument may range from few weeks to 30 years. A policymaker may rely on marketable securities, as well as on loans from financial institutions and on savings bonds sold to personal investors. Which instruments policy makers choose depends on the objective they pursue as well as on the circumstances in which the choice is made. Debt management we can define as the process of establishing and executing a strategy for managing the government's debt in order to raise the required amount of funding, achieve its risk and cost objectives, and to meet any other sovereign debt management goals the government may have set, such as developing and maintaining an efficient market for government securities. The objective of debt management policy is to minimize over the long term the cost of meeting the government's financing needs, taking account of risk connecting with debt portfolio. Application of debt management in real economy covers for example these specific issues: Debt management objectives and strategy, coordination with fiscal and monetary policy, allocation of responsibilities and objectives among institutions and authorities dealing with debt management, transparency to public, institutional framework, technical and information base. Importance of public debt management results from facts that high levels of public debt are a common feature of modern economies. It is possible to suppose that debt management is going to be very actual issue in the Czech Republic in near future for these reasons -- Czech Republic is small and open economy (we can consider it to be emerging market), during last several years public debt in Czech Republic have been growing rapidly not only in absolute volume but also as GDP ratio, there is a permanent danger that financial and economic shocks in international economy combined with inappropriate fiscal and monetary policy can have negative or in extreme case fatal impact on many people living in the Czech Republic. Dissertation "Public debt Management" primary focused on these issues and problems: Basic theoretical points concerning fiscal policy, deficit and public (government) debt -- methodology of measuring debt, influence debt on economy, risks connecting with public (government) debt Arguments for and against deficit and debt Public debt management -- general recommendations of International Monetary Fund Practice as for the public debt management in some countries -- USA, Sweden, countries of Euro-area Situation as for the public debt in Czech Republic Public debt management in Czech Republic -- historic development, goals and criteria set and used presently, analyze of risks that public debt management deals with, risk management applied in Czech republic, evaluation public debt management in Czech republic -- confrontation with recommendations of International Monetary Fund Analyze of impact of financial crises on process of public debt management in Czech republic Some arrangements concerning directly or indirectly public dept management in Czech Republic are recommended and analyzed. These recommendations are: Implementation of "inflation-linked" bonds Increasing portion of debt denominated in euro currency Prolongation of calendar of emissions Improvement of intelligibility of documents named "Strategie" that should declare and explain principles of public debt management in Czech republic Creation and implementation of special law destined for public debt management
