This paper assesses the economic impacts of the Swiss climate policy formulated under the Kyoto Protocol; the impacts on the carbon price, the welfare cost, and trade effects are examined. Our analysis is based on a multi-sectoral and multi-regional, computable general equilibrium (CGE) model of the world economy (GEMINI-E3) which includes a representation of the Swiss economy. The model is use...

We analyze the welfare e¤ect of governmental regulation for individuals who consider anticipated regret in their decision making process. While governmental policies by directing choice distort individual decisions in the private market they can alleviate individuals’pain associated with the feeling of regret. We specify a general model to highlight this trade-o¤ and investigate two policies mo...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

The stylized facts suggest a negative relationship between tax progressivity and the skill premium from the early 1960s until the early 1990s, and a positive one thereafter. They also generally imply rising tax progressivity, except for the 1980s. In this paper, we ask whether optimal tax policy is consistent with these observations, taking into account the demographic and technological factors...

This paper analyzes the behavior of the tax revenue to output ratio over the business cycle. In order to replicate the empirical evidence, we develop a simple model combining the standard Ak growth model with the tax evasion phenomenon. When individuals conceal part of their true income from the tax authority, they face the risk of being audited and hence of paying the corresponding …ne. Under ...

This paper presents a brief overview of the extant fiscal situation in South Asian countries. In particular, I emphasize low tax/GDP ratios and inelastic expenditure/GDP ratios which then lead to structurally entrenched fiscal deficits. The paper also reports on the sustainability of fiscal and current account deficits in the South Asian countries. Finally, the paper reports on some important i...

Using the Mirrlees optimal income tax model, with no income e¤ects on labour supply, this article shows that the discrete population approach provides new insights into the characterization of the optimal tax system, which complements the previous …ndings. The analysis is based on the "Spence-Mirrlees wedge" which corresponds, at each observed gross income level, to a ratio between the marginal...

a r t i c l e i n f o JEL classification: E62 H22 O41 Keywords: Two-sector model Human capital Optimal factor tax incidence This paper studies the optimal factor tax incidence in a standard two-sector, human capital-based endoge-nous growth model elucidated by Lucas (1988). Capital income taxes generate dynamic inefficiency for capital accumulation and labor income taxes create dynamic ineffici...
