The Differential Impact of Public and Private Governance Institutions on the Different Modes of Foreign Investment

This paper examines the respective impacts of public and private governance institutions on foreign direct and foreign portfolio investment inflows. We present two hypotheses: (1) there is a strong correlation between the quality of a country’s public governance institutions and the amount of foreign direct investment (FDI) received while the quality of its private governance institutions has no further discernible impact on this correlation; (2) there is a strong correlation between the quality of a country’s public governance institutions and the amount of foreign portfolio investment (FPI) received while the quality of its private governance institutions has a further positive impact on this correlation. Our findings, which are based on panel data analysis, show both hypotheses to be valid.     

Network modeling approaches for calculating wholesale NGA prices: A full comparison based on the Greek fixed broadband market

According to the European Commission Recommendation for setting copper and fiber wholesale prices where cost orientation is imposed as a remedy, National Regulatory Authorities (NRAs) should adopt a Bottom-UP Long-Run Incremental Cost Plus (BU LRIC+) costing methodology that estimates the current cost that a hypothetical efficient operator would incur to build a modern efficient Next Generation Access (NGA) network. The starting point of modeling an efficient operator investing in NGA networks is the network modeling approach. In this paper, we compare the most widely adopted network modeling approaches in terms of wholesale fiber-to-the-home (FTTH) prices. In particular, the modified scorched node approach is compared to the extreme cases of the scorched node and the scorched earth approaches. The comparison between the aforementioned scenarios sheds light on the impact of each approach on the wholesale FTTH prices. The main finding of this paper is that the scorched earth approach leads to a maximum of 10% reduction in the short-term access prices compared to the most inefficient scorched node approach, whereas further extending its optimizations by optimizing the number of central offices, both the short-term and long-term wholesale price reductions are quite significant (more than 20%) regardless of service speeds. Consequently, NRAs should consider a geographically differentiated modeling approach when regulating the wholesale market by adjusting the level of scorching in each area and network segment according to the investment plans of telecom operators. An appropriate variation of the modeled network operator's efficiency is expected to more accurately represent the costs of a reasonably efficient operator based on the real market conditions and a forward-looking perspective. These findings provide valuable information to both network operators and telecom regulators.     

MACROECONOMIC LINKAGES IN MEXICO

The authors study the effects of selected macro variables on output in Mexico, following a Kaleckian framework, and using a probabilistic approach to econometrics. They find a strong positive effect of US GDP, of protection of the domestic market and of government expenditure, on Mexico's GDP, and a negative influence of higher exchange rate and credit rationing. Their results support the overall outlook proposed by the post Keynesian and the Latin American Structuralist schools of economic thought, and reject the Washington Consensus type of policies Mexico has been following during the last decades.
