Parameterized thermal macromodeling for fast and effective design of electronic components and systems
We present a parameterized macromodeling approach to perform fast and effective dynamic thermal simulations of electronic components and systems where key design parameters vary. A decomposition of the frequency-domain data samples of the thermal impedance matrix is proposed to improve the accuracy of the model and reduce the number of the computationally costly thermal simulations needed to build the macromodel. The methodology is successfully applied to analyze the impact of layout variations on the dynamic thermal behavior of a state-of-the-art 8-finger AlGaN/GaN HEMT grown on a SiC substrate
Willingness to pay for a local food label for lamb meat in Spain
The aim of the paper is to assess consumers’ willingness to pay (WTP) for a local food produced in a less-favoured area in the Aragon region (Spain). In particular, we examine whether consumers value lamb meat products (lamb and suckling lamb) labelled as “Ojinegra from Teruel”, traditionally produced in these area. We use a nonhypothetical experimental auction to elicit Spanish consumers’ WTP for “Ojinegra from Teruel” labelled lamb products. Results show that consumers are willing to pay a positive premium for a lamb and suckling lamb labelled as “Ojinegra from Teruel
On the use of honesty priming task to mitigate hypothetical bias in choice experiments
We test whether the use of an honesty priming task from the social psychology
literature can help mitigate hypothetical bias in stated preference choice experiments (CE).
Using a between-sample design, we conducted experiments with five treatments: (1)
hypothetical CE without cognitive task, (2) hypothetical CE with cheap talk script, (3)
hypothetical CE with neutral priming task, (4) hypothetical CE with honesty priming task,
and (5) non-hypothetical CE. Results generally suggest that marginal willingness to pay
estimates from treatment 4 where subjects are given honesty priming task before the choice
experiment are not statistically different from marginal valuations from treatment 5 where
subjects are in a non-hypothetical choice experiment. Values from both these treatments are
significantly lower than those from other three hypothetical treatments (treatments 1-3).
Using hold out tasks, our results also suggest that one could get higher correct predictions of
participants’ choices in treatments 4 and 5 than in treatments 1-3 and that there is no
significant difference in percentage of correct predictions between treatments 4 and
Importance of Social Influence in Consumers' Willingness to Pay for Local Food: Are There Gender Differences?
The authors assess consumers' willingness to pay (WTP) for a local food product using an experimental auction. As local foods involve a social component, they aim also to test if social influence affects WTP for local foods and if the effects of social influence on WTP are different between men and women. They found that consumers are willing to pay a premium for the analyzed local food product. Moreover, social influence indeed affects WTP values, but the effects are different between men and women. Although social influence positively affects WTP for local foods for women, the effect is negative for men. The results have significant marketing and policy implications related to the promotion of local foods.Peer Reviewedexperimental auctionlabellamb meatSpainwillingness to payPublishe
Participants’ competitiveness and bidding behaviour in experimental auctions: an application to the Spanish market
The aim of the paper was to examine if experimental auctions are demand revealing
regardless the level of participants’ competitiveness. Then, we design an experimental
auction with two treatments to check if the level of participants’ competitiveness does
affect their bidding behavior. Both treatments had all the same designed characteristics
except that in the second treatment, participants who reported the highest levels of
competitiveness were not allow to participate in the auction. Then, we could directly
compare bids from both treatments to test differences in bidding behavior between them.
Our findings generally indicate that the level of participants’ competitiveness does not
affect bidding behavior and then, homegrown experimental auctions are demand revealing
in practice regardless the level of participants’ competitiveness.demand revelationlamb meatSpainOjinegra from TeruelPublishe
Time domain dynamic electrothermal macromodeling for thermally aware integrated system design
Time domain identification of reduced dynamic thermal models is pursued with well established macromodeling techniques, providing electrical equivalents to be integrated in standard circuit simulators. Self and mutual thermal impedances of electronic structures, preliminarily evaluated through accurate 3-D FEM thermal simulations, are directly identified with Time Domain Vector Fitting and synthesised in a lumped PSPICE circuit. Two relevant examples of dynamic electrothermal co-simulation are given, the results of which exhibit significant differences with respect to their isothermal counterpart
Consumer’s willingness to pay for sustainable food products: do food miles labels matter?
This paper analyses consumers’ preferences and willingness to pay for food products (i.e.,
almonds) carrying organic and/or “food miles” labels in Spain. Using data from a nonhypothetical
choice experiment, a Random Parameter Logit model and an Error Component
Random Parameter model with correlated errors are estimated to assess the effect of these
labels on consumers’ utility. Results suggest that consumers are willing to pay more for a
product with “food miles” label indicating that the product is locally grown than a product
without “food miles” label. However, products with “food miles” labels denoting longer
distances are valued less than products without “food miles” labels. Results imply that
locally grown products are valued more than organic food products. Based on the marginal
WTPs, our results also suggest that the least valued product would be the non-locally
grown conventional almond. Relative to this product, respondents are willing to pay 0.61 €
more for a non-locally grown organic product, 1.51 € more for a locally grown
conventional product, and 2.12 € more for a locally grown organic product
