while ignoring income distribution and estimating aggregate demand generally leads to aggregation bias and thus, does not reflect households’ demand properly, yet aggregation bias is rarely considered in empirical demand studies and simply is ignored in most cases. the objective of the present study is to estimate aggregation bias in households’ demand for various types of meats and to evaluate...

The directed search model (Peters, 1984) is static; its dynamic extensions typically restrict strategies, often assuming price or match commitments. We lift such restrictions to study equilibrium when search can be directed over time, without constraints and at no cost. In equilibrium trade frictions arise endogenously, and price commitments, if they do exist, are self-enforcing. In contrast to...

Transitory price changes, namely short lived deviations from a reference price level, are prominent in the data but do not fit neatly in standard sticky price models. We analyze a sticky price model where a firm chooses a price plan, namely a set of 2 prices. Changing the plan entails a menu cost, but either price in the plan can be charged at any point in time. The setup generates a persistent...

Abstract Using two basic assumptions of time series analysis, a test is proposed to assess the quality of seasonal adjustment of a series. The test is applied to several seasonally adjusted series of the Consumer Price Index (CPI) using three methods of seasonal adjustment: State Space Model Based Method (SSMB), TRAMO SEATS Method and X12ARIMA method. The empirical results are presented along w...

I here recall Ryle's analysis of Heterologicality, but broaden the discussion to comparable analyses not only of Heterologicality but also other puzzles about self-reference. Such matters have a crucial bearing on the debate between representational and non-representational theories of mind, as will be explained. 1 [1] The most remarkable thing about the so-called Heterologicality Paradox is th...

Abstract We present geodetic mass-balance estimates for ten glaciers (22.6 ± 1.1 km 2 ) around Volcán Domuyo between 1962 and 2020 (and 46 covering 29 1.5 1984 2020), derived from airborne, ASTER Pléiades imagery. Overall, we find a slightly negative mass balance (−0.15 0.09 m w.e. –1 the entire 1962–2020 time span. A closer inspection of sub-periods reveals, however, an increasingly with time....

the increasing consumption of electricity in iran is one of the greatest concerns of the government. using the subsidy-based pricing system is one of the main reasons of improper pattern of residential electricity consumption that has imposed great cost over the government due to the increased number of consumers and their improper way of consuming electricity. in this paper, we analyze the fac...
