Regional Economic Policy Transition in the Local Government of Korea

Regional economic policy in developing countries is dominated by central government. The potential of local government has recently attracted more interest (Eisiger 1988; Fosler 1988; Beckeman 1996; Jones 1990 ; Elkins 1966; Kossy; 1966; Leicht 1994). The general consensus is that local business climate manifests either entrepreneurial conditions. Since the early 1970s, local governments in Korea confine their policies for its diversification due to an incomplete financial environment. There has been increased public awareness that regional economic policies should be designed to give local authorities raising local organizational capacity as well as ensuring a greater equality in the allocation of funding and priorities. This study discusses regional economic policy and can summarize as follows; First, most local governments in Korea tend to adopt supply-led policies than the demanded one because of limited local resources and inexperience in its policy formulation/ implementation. Local government leaders, however, are increasingly aware of the importance of demand-led regional economic policy. This means that the entrepreneurial approach to economic development at the local level is being gradually imbedded after initiating local governance as a result of 1997 financial crisis in Korea. Second, the more wealthy, urban and industrial regions are the most innovative in every policy domain promoting regional economic development; this can be interpreted the urban areas have better access to financial/ human resources along with urban government officials having more experience in policy planning and implementation from their favorable resources. Third, there is a high correlation between policy environment factors and regional economic policy tools, particularly with the participation of private sector. The entrepreneurial approach to regional economic development is a crucial element in a firm's capability along with creation of the favorable business climate. Local governments with diverse regional economic policies tend to be associated with high government level and have more financial resources, expertise and a strong local leadership available to them. By contrast, the local governments with weaker regional economic programs are likely to be noted for poorer relationships with low level of policy environmental factor. Therefore, the central government needs to play a coordinated role of resource allocation for less favored regions in order to be diversify/ intensify regional economic development.

Weak type estimates on certain Hardy spaces for smooth cone type multipliers

Let $\varrho\in C^{\infty} ({\Bbb R}^d\setminus\{0\})$ be a non-radial homogeneous distance function satisfying $\varrho(t\xi)=t\varrho(\xi)$. For $f\in\frak S ({\Bbb R}^{d+1})$ and $\delta>0$, we consider convolution operator {\Cal T}^{\delta} associated with the smooth cone type multipliers defined by \hat {{\Cal T}^{\delta} f}(\xi,\tau)= (1-\frac{\varrho(\xi)}{|\tau|} )^{\delta}_+\hat f (\xi,\tau), (\xi,\tau)\in {\Bbb R}^d \times \Bbb R. If the unit sphere $\Sigma_{\varrho}\fallingdotseq\{\xi\in {\Bbb R}^d : \varrho(\xi)=1\}$ is a convex hypersurface of finite type and $\varrho$ is not radial, then we prove that {\Cal T}^{\delta(p)} maps from $H^p({\Bbb R}^{d+1})$, $0<p<1$, into weak-$L^p(\Gamma_{\gamma})$ for the critical index $\delta(p)=d(1/p -1/2)-1/2$, where $\Gamma_{\gamma}=\{(x,t)\in {\Bbb R}^d\times\Bbb R : |t|\geq\gamma |x|\}$ for $\gamma=\max\{\sup_{\varrho(\xi)\leq 1}|\xi|,1\}$. Moreover, we furnish a function $f\in\frak S({\Bbb R}^{d+1})$ such that \sup_{\lambda>0} \lambda^p|\{(x,t)\in \bar{{\Bbb R}^{d+1}\setminus\Gamma_{\gamma}} : |{\Cal T}_{\varrho}^{\delta(p)}f(x,t)|>\lambda\}|=\infty.Comment: 13 page

Estimating Chinese Interprovincial OutPut Spillovers with Provincial Input-Output Tables

This paper aims at estimating productivity improvement of Chinese 17 relatively backward provinces in manufactures through importing manufactured intermediates from advanced provinces on the basis of just published 2002 national and provincial input-output tables. As Chinese regional inequality remains large, North-South spillover models of trade are appropriate to guide this study. Applying reliable methods to approximate net interprovincial imports by province and sector and the allocation of imported manufactured inputs among sectors within each province, we use a Cob-Douglas production function incorporating Dixit-Stiglitz type increasing returns to variety to deal with the manufactured inputs, and treat the output spillovers as one part of total factor productivity. According to our estimations, as expected, interprovincial imports of manufactured inputs have significant impacts on industrial sectors as well on all sectors of these provinces.Chinese interprovincial trade;North-South spillovers;input-output tables;regional inequality;imported intermediates

The dynamically induced Fermi arcs and Fermi pockets in two dimensions: a model for underdoped cuprates

We investigate the effects of the dynamic bosonic fluctuations on the Fermi surface reconstruction in two dimensions as a model for the underdoped cuprates. At energies larger than the boson energy $\omega_b$, the dynamic nature of the fluctuations is not important and the quasi-particle dispersion exhibits the shadow feature like that induced by a static long range order. At lower energies, however, the shadow feature is pushed away by the finite $\omega_b$. The detailed low energy features are determined by the bare dispersion and the coupling of quasi-particles to the dynamic fluctuations. We present how these factors reconstruct the Fermi surface to produce the Fermi arcs or the Fermi pockets, or their coexistence. Our principal result is that the dynamic nature of the fluctuations, without invoking a yet-to-be-established translational symmetry breaking hidden order, can produce the Fermi pocket centered away from the $(\pi/2,\pi/2)$ towards the zone center which may coexist with the Fermi arcs. This is discussed in comparison with the experimental observations.Comment: Some comments and references were added and typos were corrected. The published version. 9 page
