This paper tests for the production complementarity between firms’ access to high-quality intermediate inputs and their skill composition joint impact on output quality. Using census data at firm-product level Ecuador 1997–2007, we exploit exogenous tariff changes Ecuador’s entry World Trade Organization show that input cuts allow firms upgrade Next, demonstrate by means of within-firm instrume...

There is significant evidence of variation in the penalties awarded in cases of plagiarism across the higher education sector, which has led to calls for standardisation of treatment. In this context, the annual reports of the Office of the Independent Adjudicator for Higher Education (OIA) in the UK have identified increases in the numbers of complaints pertaining to judgements of academic mis...

An attractive approach to managing electricity demand in the Smart Grid relies on real-time pricing (RTP) tariffs, where customers are incentivized to quickly adapt to changes in the cost of supply. However, choosing amongst competitive RTP tariffs is difficult when tariff prices change rapidly. The problem is further complicated when we assume that the price changes for a tariff are published ...

In recent years, firms in a number of industries have introduced wide menus of pricing plans that grant access to a virtually identical product under different pricing schemes. These menus of tariffs allow consumers to self-select into the tariff that best fits their demand. They include pure pay-per-use tariffs, tariffs where the consumer pays an access price, and a marginal price only for usa...

In many service industries, firms introduce three-part tariffs to replace or complement existing two-part tariffs. While both twoand three-part tariffs have been studied in the extant literature, to our best knowledge there have been no empirical studies of customer choice and usage when both types of tariffs are on offer. A pertinent question in that context is whether three-part tariff usage ...

An integrated transport system is the way how to provide transport service in the region by integrating all modes of transport. The design of this system is connected with solving of several optimization problems such as coordination of connections in transport modes, optimization of connection supply, minimization of time losses related to the changing of travel connection and the design of th...

In communication, information, and other industries, three-part tariffs are becoming increasingly popular. A three-part tariff is defined by an access price, a usage allowance, and a marginal price for any usage in excess of the allowance. The nonlinear-pricing literature has focused primarily on two-part tariffs. We show that consumer behavior differs under three-part tariffs, in particular re...
