Integration of Slovenia into EU and global industrial networks: review of existing evidence

Slovenia is a small economy, which is somehow "condemned" to be open and highly internationalised. Relatively high shares of exports and imports in GDP indicate that the economy is highly dependent on foreign markets and inputs. This orientation is additionally strengthened by the final stage of the transition process and accession to the EU, both meaning definite opening of the economy and its integration into EU and global economy. Internationalisation of operations is, therefore, increasingly becoming a critical factor for creating and stimulating a competitive corporate sector in Slovenia. To strengthen the internationalisation processes, the policy of internationalisation should be based on the following: (i) lifting barriers to internationalisation; (ii) taking the actual needs of companies as a starting point; (iii) flexibility, transparency and the long-term perspective; (iv) adaptability and a re-examination of policy; and (v) a holistic concept of internationalisation. Increasingly important aspects of internationalisation are inward and outward FDI. The paper review the existing evidence on the internationalisation of Slovenian economy in all the various modes. The paper is composed of three parts. In the first part the scale and dynamics of industry integration of Slovenia into EU/global industrial networks by the way of foreign trade, outward and inward processing trade (OPT) and subcontracting and FDI is given. The second part analyses the integration of Slovenian car components industry in international industrial networks, and the third part concentrates on the motivation and strategies of foreign investors in Slovenia and Slovenian investors abroad

Third-order magnetic susceptibility of the frustrated square-lattice antiferromagnet

We present results from our analysis of the finite-temperature properties of the spin 1/2 $J_{1}$-$J_{2}$ Heisenberg model on a square lattice. The analysis is based on the exact diagonalization of small clusters with 16 and 20 sites utilizing the finite-temperature Lanczos method. In particular, we focus on the temperature dependence of the third-order magnetic susceptibility as a method to resolve the ambiguity of exchange constants. We discuss the entire range of the frustration angle $\phi=\tan^{-1}(J_{2}/J_{1})$ parameterizing the different possible phases of the model, including the large region in the phase diagram with at least one ferromagnetic exchange constant.Comment: 2 pages, 2 figure

Optical conductivity of colossal magnetorestistance compounds: Role of orbital degeneracy in the ferromagnetic phase

Recent optical conductivity $\sigma(\omega)$ experiments have revealed an anomalous spectral distribution in the ferromagnetic phase of the perovskite system $La_{1-x}Sr_xMnO_3$. Using finite temperature diagonalization techniques we investigate $\sigma(\omega)$ for a model that contains only the $e_g$-orbital degrees of freedom. Due to strong correlations the orbital model appears as a generalized t-J model with anisotopic interactions and 3-site hopping. In the orbital t-J model $\sigma(\omega)$ is characterized by a broad incoherent spectrum with increasing intensity as temperature is lowered, and a Drude peak with small weight, consistent with experiment. Our calculations for two-dimensional systems, which may have some particular relevance for the double-layer manganites, show that the scattering from orbital fluctuations can explain the order of magnitude of the incoherent part of $\sigma(\omega)$ in the low temperature ferromagnetic phase. Moreover orbital correlation functions are studied and it is shown that $x^2$-$y^2$ orbital order is prefered in the doped planar model at low temperature.Comment: Revtex, 14 pages, 14 figure

Outward FDI from Slovenia and its policy context

High export orientation originating from a small domestic market and experience in outward foreign direct investment (OFDI) from the pre-transition period helped Slovenian enterprises to internationalize early on after their country's independence and separation from the former Republic of Yugoslavia, making Slovenia one of the first outward investors among transition economies in South-East Europe. This facilitated a reorientation of international trade and investment toward developed economies after the loss of the Yugoslav market triggered by Slovenian independence. OFDI flows increased rapidly after the end of the 1990s. Following the global financial and economic crisis, OFDI flows fell significantly in 2009 and 2010, and in 2010, the OFDI stock decreased for the first time since 2000. With the help of OFDI, Slovenia's enterprises have grown considerably beyond the constraints imposed by the country's dynamic, but small, economy. Their foreign expansion is in line with national strategic priorities that include entrepreneurship, business internationalization and innovation

Spectral properties of the planar t-J model

The single-particle spectral functions $A({\bf k},\omega)$ and self-energies $\Sigma({\bf k},\omega)$ are calculated within the $t-J$ model using the finite-temperature Lanczos method for small systems. A remarkable asymmetry between the electron and hole part is found. The hole (photoemission) spectra are overdamped, with ${\rm Im} \Sigma \propto \omega$ in a wide energy range, consistent with the marginal Fermi liquid scenario, and in good agreement with experiments on cuprates. In contrast, the quasiparticles in the electron part of the spectrum show weak damping.Comment: 4 pages, RevTeX, 4 Postscript figure

Factors affecting farm productivity in Bulgaria, Hungary, Poland, Romania and Slovenia after the EU-accession and likely structural impacts

The paper is investigating the recent evolution of farm productivity in five EU New Member States (NMS): Bulgaria, Hungary, Romania, Poland and Slovenia. More precisely, the paper deals with determinants influencing farm productivity in a changing market and policy environment brought by their full integration to the CAP. With a combination of multivariate statistics and econometric techniques, it attempts to identify and explain the patterns of agricultural labour productivity change in the period 2003-2005. Results suggest that adjustment patterns are diverging and are region-specific, depending mainly on the initial farm structural conditions, and availability of non-farm jobs. Policy implications of the paper suggest that agricultural policy should move away from the concept of transfers to agriculture to more pro-active role in creating conditions for job creation in rural areas.structural adjustment, farm productivity, farming types, EU-accession, Community/Rural/Urban Development, Q12, R11,

Raman Response in Doped Antiferromagnets

The resonant part of the $B_{1g}$ electronic Raman scattering response is calculated within the $t-J$ model on a planar lattice as a function of temperature and hole doping, using a finite-temperature diagonalization method for small systems. Results, directly applicable to experiments on cuprates, reveal on doping a very pronounced increase of the width of the two-magnon Raman peak, accompanied by a decrease of the total intensity. At the same time the peak position does not shift substantially in the underdoped regime.Comment: 11 pages revtex, 3 postscript figures.
