Posting a menu of three-part tariffs is a widespread phenomenon in the telecommunication industry. The paper provides a characterization of the implementability of allocation rules involving bunching in the linear framework of Mussa and Rosen [5]. I show that an allocation rule is non-decreasing if and only if it is implementable by a menu of threepart tariffs. Furthermore, I extend the notion ...

Tariff bindings and administered protection are two characteristics of the WTO that are little understood. Tariff bindings place a ceiling on tariffs that is not always reached, while administered protection ensures that all sectors have access to some minimum import protection, effectively creating a floor for protection. How do these policies affect applied MFN tariff rates that are enacted t...

We measure the effects of trade liberalization over the period of 1993-2002 on regional poverty levels in 259 Indonesian regions, and investigate the labour market mechanisms behind these effects. The identification strategy relies on combining information on initial regional labour and product market structure with the exogenous tariff reduction schedule over four three-year periods. We distin...

This paper develops a stylized economic model for passenger transport in the greater Oslo area, which agents' choices of car ownership, pattern, and electric vehicle (EV) charging are jointly determined. If enough EVs charge during peak hours, costly grid expansions may be needed. We examine how distribution system operators can mitigate these costs with different pricing schemes this, turn, af...

Renewable energy communities (RECs) are prominent initiatives to provide end consumers an active role in the sector, raise awareness on importance of renewable (RE) technologies and increase their share system thus reducing greenhouse gas (GHG) emissions. The economic viability RECs though, depends multiple interdependent factors that require careful examination for each individual context. Thi...

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and Rodriguez-Clare (2012) to encompass revenue-generating import tariffs. Our formula permits easy quantification...

ABARE project 1653 Natural gas demand forecasts are used by regulatory bodies when setting transmission and distribution tariffs. Reviews of current forecasting methodology used by gas companies indicate that the current approaches may be inappropriate for forecasting gas demand. The modeling methodology for gas demand forecasting and the implications of the results for the regulation of transm...

The electric industry has gone through dramatic changes over the past two decades. The restructuring program begun in the early 1990s opened up the wholesale markets with numerous competitive generation companies transacting over open-access transmission systems. New entities called independent system operators (ISOs) and regional transmission organizations (RTOs) arose as wholesale market oper...

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can be interchangeable wi...
