Does the Rank-size Rule Matter in Indonesia? Determinants of the Size Distribution of Cities

In Indonesia the cities have continously grown. However they varied in size. Some cities have the population above two million citizens, while some have below than fivehundred thousands. Some economic factors are hypothesized to influence such distribution. This study aims to test the rank-size rule (Zipf's law) and to find thedeterminants of size distribution of cities. The panel data method is employed to satisfy the objectives of study. All district and provincial level data are used for year 1995, 2000 and 2005. The pareto exponent shows that the rank-size rule does not matter in Indonesia.Level of agglomeration economies, local government expenditure and number of administrative city increases the concentration of size of cities. The labor force participation and region's openness affects the size of cities to be more equally distributed

Does size matter?

For isolated objects in complete darkness, retinal image size contributes to distance judgments even if the true object size is unknown. Here we show that the same is true under more natural conditions. On a wide beach we positioned a red cube at 10–20 m distance and then asked subjects to walk to it while blindfolded. Subjects never had a close view of the cube and were unaware that on separate trials cubes with sides of 15 cm and 20 cm were positioned at the same locations. On average, subjects walked 1 m further after seeing the 15 cm cube than after seeing the 20 cm cube

Failures of the complex infrastructures society depends on having enormous human and economic cost that poses the question: Are there ways to optimize these systems to reduce the risks of failure? A dynamic model of one such system, the power transmission grid, is used to investigate the risk from failure as a function of the system size. It is found that there appears to be optimal sizes for such networks where the risk of failure is balanced by the benefit given by the size

Size Does Matter: International Trade and Population Size

Classical theory of international trade has long advocated trade liberalization and open borders. However, this process is not necessarily beneficial to all countries involved. This paper focuses on two modeled economies that initially share the same technology and per-capita income, but differ in population size. With trade, the profit of the large duopolist is reduced to the benefit of the duopoly in the smaller country, as the large country is no longer able to benefit from its larger population. This may explain why one country would want to open trade with high barriers while another country would prefer low barriers.Duopoly, Free Trade, Protectionism, Population Size, Nash Equilibrium

Size Does Matter (in P2P Live Streaming)

Optimal dissemination schemes have previously been studied for peer-to-peer live streaming applications. Live streaming being a delay-sensitive application, fine tuning of dissemination parameters is crucial. In this report, we investigate optimal sizing of chunks, the units of data exchange, and probe sets, the number peers a given node probes before transmitting chunks. Chunk size can have significant impact on diffusion rate (chunk miss ratio), diffusion delay, and overhead. The size of the probe set can also affect these metrics, primarily through the choices available for chunk dissemination. We perform extensive simulations on the so-called random-peer, latest-useful dissemination scheme. Our results show that size does matter, with the optimal size being not too small in both cases

Seller strategies on eBay: Does size matter?

We examine seller strategies in 1177 Internet auctions on eBay, to understand the diversity of strategies used, and their impacts. Dimensions of strategic choice include the use of a ‘Buy it Now’ option, the level of the starting price, and the use of a secret reserve price. A major focus of our analysis is on differences across sellers with different volumes of sales. The largest volume sellers (termed “retailers”) in our sample employ uniform selling strategies, but lower volume sellers exhibit a wide variety of strategic choices. While some components of sellers’ strategies appear important in raising seller revenue, including starting the auction with a ‘Buy it Now’ offer, the overall impact of seller strategy choices on the outcome appears to be quite small. We interpret this as evidence for the competitiveness of the online auction market for frequently traded items with conventional retail alternatives. An exception is provided by the use of a secret reserve price, which raises the winning bid conditional on a sale, but reduces the probability of a sale. Depending on sellers’ risk aversion and impatience, this may also be an efficient outcome
