Are there economies of scale to data in internet search? This paper is first to use real search engine query logs to empirically investigate how data drives the quality of internet search results. We find evidence that the quality of search results improve with more data on previous searches....

This study compares the responsiveness of microcredit interest rates to age, scale of lending and organisational charter. It uses an unbalanced panel of 300 MFIs from 107 developing countries from 2005 to 2015. Three key trends emerge from the results of a 2SLS regression. First, the adoption of...

Equivalence scales are often used to adjust household income for differences in characteristics that affect needs. For example, a family of two is assumed to need more income than a single person, but not double due to economies of scale in consumption. However, in comparing economic well-being...

This paper applies recent developments in collective model estimation to elicit the household resource sharing rule, i.e. the amount of household resources accruing to fathers, mothers, and their children among African families in South Africa. We use the 2010/11 South African Income and...

The paper unveils the market structure of container shipping, which suffers by many interpretations. Existing models regress between contestability, duopoly, monopolistic competition and game theory. This paper proposes an oligopoly model with two groups of companies: oligopolists and...

Voters dealing with jurisdictional merger decisions face a trade-off between economies of scale and preference costs. Larger jurisdictions may offer cost advantages, yet the downside is that policies in larger units may be less aligned to voter preferences. Our study is the first to provide...

There is a growing body of evidence that interest rate spreads in Africa are higher for big banks compared to small banks. One concern is that big banks might be using their market power to charge higher lending rates as they become larger, more efficient, and unchallenged. In contrast, several...

Standard open economy macro models with unemployment predict a contractionary short-run effect of international capital inflows. Empirical evidence, on the other hand, often associates such inflows with short-term booms, and developing country policy makers frequently go out of their way to...

This article examines the empirical performance of alternative frontier estimators' ability to replicate a known underlying technology and economic measures such as multi-product and product-specific economies of scale, and economies of scope. A cross sectional Monte Carlo procedure to simulate...

This paper explores (dis-)economies of scale in property value assessment via cooperative agreements among small tax assessing jurisdictions without consolidation. New York State incentivizes small neighboring towns to unify their assessment function while maintaining respective tax authority;...

We study the fiscal consequences of municipal mergers by making use of a largescale merger reform in the German federal state of Brandenburg. This reform, which was implemented from 2001 to 2003, led to a substantial reduction in the number of municipalities. Individual mergers were...

Potable water supply in Germany is highly fragmented. A consolidation of the industry could, therefore, lead to lower cost of water supply and price savings for the customers. In this paper we estimate a total cost function for potable water supply based on a unique sample of German water...

We propose a novel structural method to empirically identify economies of scale in household consumption. We assume collective households with consumption technologies that define the public and private nature of expenditures through Barten scales. Our method recovers the technology by solely...

Combining micro and macro data, we construct demand-side shocks, which we take to be exogenous for individual firms. We estimate a reduced-form model to describe how firms adjust their production, employment, capital stock, and inventories in response to such shocks. Then, we chose the...

Iceberg transport costs are one of the main ingredients of modern trade and economic geography models: transport costs are modelled by assuming that a fraction of the goods shipped "melts in transit". In this paper, we investigate whether the iceberg assumption applies to the costs of...

There is a growing body of evidence that interest rate spreads in Africa are higher for big ba nks compared to small banks. One concern is that big banks might be using their market power to charge higher lending rates as they become larger, more efficient, and unchallenged. In contra st,...

Banking models in the tradition of Diamond and Dybvig (1983) rely on sequential service to explain belief-driven runs. But the run-like phenomena witnessed during the financial crisis of 2007-08 occurred in the wholesale shadow banking sector where sequential service is largely absent,...

DEA models help a DMU to detect its (in-)efficiency and to improve activities, if necessary. Efficiency is only one economic aim for a decision-maker; however, up- or downsizing might be a second one. Improving efficiency is the main topic in DEA; the long-term strategy towards the right production...

This study investigates the legitimacy of the relatively high interest rates charged by those microfinance institutions (MFIs) which have been transformed into regulated commercial banks using information garnered from a panel of 1232 MFIs from 107 developing countries. Results show that...

Specialization in agricultural systems leads to trade-offs between economic gains and ecosystem functions. Economic gains can be maximized when production activities are specialized at increasingly broader scales (from the household to the village, region or above), particularly when markets for...

This paper discusses the process of European institutional integration from a political-economy perspective, linking the long-standing political debate on the nature of the European project to the recent economic literature on political integration and disintegration. First, we introduce the...
