Here is a note from Economist on Slovenia:
Slovenia was already economically advanced by regional standards when it gained independence, so that it has experienced slow growth rates relative to other central European economies, and has adopted a more complacent attitude towards privatisation and economic reform... The main economic policy issues include the privatisation process and attempts to improve the business environment. Progress on both is made difficult by the consensus-based nature of policymaking.

The empirical argument in favor of privatization is that the allocation of scarce resources is more efficient in private economy than in public sector regardless of the economy's sector. The only argument that could speak against privatization is the establishment of natural monopolies in case if competitive code is not fully enforced. In this case, control over natural monopolies is needed to prevent price speculations that could occur at the expense of consumer welfare.
The quality of Slovenia's business environment is restrained by administrative burden, restrictive labor regulation and high tax burden which disables the creation of productive behavior. The total number of reforms in Slovenia regarding the ease of doing business is zero (link).
The product quality of the country's business environment is, by competitive analysis, as any other market product. Higher the quality supplied (the number of implemented reforms to improve business environment), higher the demand for the product (the number of investors going for business in Slovenia and the growth of start-ups, spin-offs, and wanna-be's) and higher the reputation of the country as an investment location.
