Loss systems are of great importance for price optimization and revenue management even after more than a century since their first appearance. In this thesis, we analyze the optimal pricing problem for an M/M/1/1 Erlang-loss systems, and apply the model to inspect the impacts of vacancy tax regulations on short-term rental hosts. We then work on M/M/N/N loss systems while considering both advance reservation and multinomial logit (MNL) choice-model for the customers. We develop a simulation for this system and then train a machine learning (ML) model based on the outputs of this simulation to predict the utilization of each server based on different queueing parameters. Finally, we train another ML model for price optimization when the decision-maker sets the price for all servers to maximize the revenue of the whole system. We show that the presence of advance reservation decreases the utilization, consequently reducing the profit in the corresponding system. / Thesis / Master of Science (MSc)

This dissertation focuses on contextual frames that influence how consumers perceive prices and how that in turn affects their product evaluations and consumption decisions. This research consists of three essays and attempts to further the understanding of contextual factors that affect how consumers perceive prices (essay 1) and how perceptions about prices influence product inferences (essay 2) and decision making (essay 3). While there is a substantial body of research on price framing and price perception, my research identifies and attempts to fill some important gaps in the existing research. In my first essay, I introduce a new price framing effect – the upper limit framing effect. This essay shows that framing the upper limit of a price estimate as less than vs. not more than can result in systematic differences in perceptions regarding the underlying price. This research contributes to the existing price framing research, which primarily focuses on set prices, by investigating price estimates. It also makes important contributions to the temporal and monetary costs and semantic framing literatures and to the literature on negations. In my second essay, I contribute to the existing perceived price-quality research that primarily concerns only the market prices. This essay shows that consumers over-apply the perceived price-quality heuristic when setting product prices by themselves (self-decided prices). Specifically, this research shows that contextual factors that affect self-decided prices in turn influence product inferences, with the relationship between contextual frame and product inferences being mediated by self-decided prices. In my third essay, I contribute to the existing price framing research by showing that in the context of multiple price presentation, the price presentation order (ascending vs. descending) affects the perceived importance of price in the decision making – an effect I term as the price order effect – an effect that is explained by prospect-theory driven loss aversion. Specifically, this research shows that descending (vs. ascending) price presentation order results in significantly lower perceived importance of price in the decision making process which in turn influences subsequent consumption decisions. In addition to the individual contributions of each essay, this dissertation makes an overall contribution to the price framing and price perception research by identifying new price framing effects and by furthering the understanding of how consumers perceive prices and how perceptions about price influences consumer decision making. / Doctor of Philosophy / This dissertation shows how different contexts can influence consumers’ perceptions about product prices. Utilizing a variety of everyday consumption products and scenarios, we show new and interesting ways in which seemingly unrelated contexts and frames can influence price perceptions. Specifically, we show that novel contexts and frames can affect (a) how consumers perceive price magnitude (essay 1), (b) how perceptions about prices influences product inferences (essay 2), and (c) how important a factor is price perceived to be in the decision making process (essay 3). Essay 1 shows that framing the upper limit of a cost estimate as (“less than” vs. “not more than”) results in different perceptions about the underlying cost. Essay 2 shows that counter to intuitive expectations, consumers utilize prices that they themselves decide to pay for a product as being indicative of its quality. Essay 3 shows that ascending vs. descending price orders results in different consumption decisions due to differential perceived importance of price in the decision making. This dissertation also discusses the several important contributions made by this research.

Master of Arts / Department of Economics / Yang M. Chang / This paper empirically examines whether there is a tendency for trade-induced price convergence - in other words if price differences among city pairs separated by a border decline with increased levels of trade. The paper examines the prices of goods in cities across Brazil and Paraguay after the implementation of MERCOSUR. Evidence of a border effect - the failure of the law of one price - between Brazil and Paraguay is found. However, the data show that since the beginning of MERCOSUR, price dispersion between Brazil and Paraguay is less for those goods that are traded more between these partners.

The purpose of this study is to see whether price endings affect people's perceptions of luxury and necessity goods. There is evidence that the rightmost digits, or endings, of retail prices can communicate meanings to consumers. Some researchers (Schindler and Kirby, 1997; Stiving and Winer, 1997; Thomas and Morwitz, 2005) argued that there are two price ending effects level effects (those effects in which consumers may underestimate the price); and image effects (those effects in which consumers may infer meaning from the right-hand digits). In the study, ninety-three participants were recruited from the University of Canterbury, Christchurch, New Zealand. All participants were given questionnaires to rate the quality and necessity-luxury of the good first; then a distraction session which used for distracting participants' attention from memorizing the prices of the goods; then a recall-test was given. Participants gave significantly different ratings for luxuries and necessities according to the different price-endings. In addition, the idea that the prices ending in 9 tend to be underestimated was also found.

This study investigated the effects of unit price structure, unit price descriptions, and unit price sequence on the demand for money in humans. Six groups of 3 participants solved multiplication problems in exchange for money under various unit prices. Consumption of money decreased as the unit price increased across all conditions. However, the data also showed that: (a) fixed price structures produced slightly more elastic demand than did variable price structures, (b) price descriptions produced more elastic demand under variable price structures but had little or no effect under fixed price structures, and (c) the alternate sequence used with fixed price structures produced slightly more elastic demand.

Master of Science / Department of Agricultural Economics / Ted Schroeder / Feeder cattle are placed into feedlots at varying weights. This placement weight is the result of procurement decisions by cattle feeders and of marketing decisions by cow/calf and stocker/backgrounder producers. Increased understanding of the behavior of these markets can help both buyers and sellers of feeder cattle make these decisions. Past research has used linear or quadratic variables or interaction variables in order to model the effects of weight on price. This study instead divides the market for feeder cattle into ten distinct subsets which are evaluated independently. The feeder cattle market for four major cattle feeding states in the Southern Great Plains (Nebraska, Kansas, Oklahoma and Texas) was divided into ten subsets, five in each gender. Each of these represent feeder cattle coming to market in a 50 pound weight range, centered upon 525, 625, 725, 825 and 925 pounds. Each of these subsets was analyzed using seven independent variables selected based upon previous research and economic rationale. These variables were the live futures price, previous feedlot returns, feeder cattle inventory, interest rate, feedlot capacity utilization, cost of gain and pasture conditions. The data for these variables were collected from public sources, aggregated into monthly observations and differenced to correct for nonstationarity. Analysis was conducted using ordinary least squares regressions. Results are reported and trends between weight classes discussed along with their implications. Findings support that feeder cattle of different weights are not perfect substitutes and that market and production factors do not influence all weights of feeder cattle the same. In fact, factors which positively and negatively affect feeder cattle price seem to signal that demand for, or in the case of pasture supply of, feeder cattle of a particular weight has changed and that placement price-weight relationships will adjust accordingly.

This thesis consists of four self-contained papers related to the Nordic electricity market. Paper [I] examine how the reform of the Nordic electricity markets has affected competition in the electric power supply market, Nord Pool. The question is if the common power market has been competitive or if electric power generators have had market power during the period 1996 -2004. Moreover, since there was a stepwise evolution from national markets to a multinational power market, we also ask how the degree of market power has evolved during this integration process. The results show that electric power generators have had a small, but statistically significant, degree of market power during the whole period.  However, studying the integration effect, i.e. how the market power has been affected by additional countries joining Nord Pool, it show that the degree of market power has been reduced and finally vanished as the market has expanded and more countries joined the collaboration. Paper [II] analyse how the deregulation of the Swedish electricity market has affected the price of electric power and how the change in electric power price, in turn, has affected consumers’ welfare. The result shows that the change in pricing principle of electric power following the deregulation has increased consumer welfare over the period studied (1996-2006), with welfare gains about 100 SEK per customer per year, indicating a three per cent welfare gain for the average customer. Paper [III] study whether (and to what extent) the multinational electricity market integration has affected the price dynamics at the Nordic power exchange. The results shows that a larger electricity market seems to reduce the probability of sudden price jumps, but also that the effect on volatility seem to depend on the characteristics, i.e. production structure, of the integrated markets. In Paper [IV] a two-stage study is conducted to investigate the extent to which shocks in the demand and supply for electricity translate into price jumps, and the extent to which this process is affected by the prevailing market structure. The main findings from the study is that whether demand and supply shocks translate into price jumps largely depends on the prevailing market structure, i.e. on how far the market works from capacity constraints. A notable feature of the empirical analysis is also that the marginal effects from positive demand and negative supply shocks on the jump probabilities are mostly insignificant and of small magnitude.

The objective of my dissertation work was to provide a better understanding of consumer choices related to these two important tradeoffs that consumers are often confronted with in the marketplace. Drawing upon regulatory focus theory, I investigated how consumers choose between price and quality or price and quantity, in each of two essays, thereby shedding light on the role of consumer goals in purchase decisions. In the first essay, I propose that quality is predominantly a promotion feature whereas price is predominantly a prevention feature. Therefore, promotion oriented consumers should be more attentive to differences in product quality whereas prevention oriented consumers should be more attentive to differences in product price. Three studies demonstrate that quality (price) is more strongly associated with a promotion (prevention) orientation, that promotion (prevention) oriented consumers prefer products with higher quality (cheaper prices), and that these preferences are mitigated when consumers do not need to prioritize between price and quality and are mediated by relative attention to quality versus price. In the second essay, I investigate the manner in which consumers' goal orientations affect their preferences for monetary versus nonmonetary promotional offers, such as bonus packs and price discounts. I propose that consumers with a promotion (vs. prevention) orientation are more likely to prefer a bonus pack offer over an economically equivalent price discount offer. Two pretests and one study provide empirical support for this key prediction. I also identify theoretically defensible and managerially actionable boundary conditions for this effect that are related to price levels and product types.

This thesis studies a single item periodic review inventory problem with stochastic demand, random price and quotation cost. It differs from the traditional inventory model in that at the beginning of each period, a decision is made whether to pay the quotation cost to get the price information. If it is decided to request a price quote then the next decision is on how many units to order; otherwise, there will be no order. An (r, S1, S2) policy with r < S2, S1 <= S2 is proposed for the problem with two prices. It prescribes that when the inventory is less than or equal to r, the price quotation is requested; if the higher price is quoted, then order up to S1, otherwise to S2. There are two cases, r < S1 or S1 <= r. In the first case, every time the price is quoted, an order is placed. It is a single reorder point two order-up-to levels policy that can be considered as an extension of the (s, S) policy. In the second case, S1 <= r, it is possible to “request a quote but not buy” if the quoted price is not favorable when the inventory is between S1 and r. Two total cost functions are derived for the cases r < S1 <= S2 and S1 <= r < S2 respectively. Then optimization algorithms are devised based on the properties of the cost functions and tested in numerical study. The algorithms successfully find the optimal policies in all of the 135 test cases. Compared to the exhaustive search, the running time of the optimization algorithm is reduced significantly. The numerical study shows that the optimal (r, S1, S2) policy can save up to 50% by ordering up to different levels for different prices, compared to the optimal (s, S) policy. It also reveals that in some cases it is optimal to search price speculatively, that is with S1 < r, to request a quote but only place an order when the lower price is realized, when the inventory level is between S1 and r.
