We study the information design problem of the contest designer in a simultaneous 2-player 2-type all-pay auction contest environment, where players have limited information about own/others valuation of the prize. We allow the players' ex ante symmetric, type distributions to be correlated, and the information disclosure policy to take the stochastic approach of Bayesian persuasion, which is a generalization of the traditional information disclosure policy. The optimal design, the structure of which depends on the degree of the correlation of players' types, is completed characterized and is shown to work better than the type-dependent information disclosure policy. This is the first study on full characterization of information design for games with two-sided asymmetric information and infinite action space. |

We propose a new seasonal adjustment approach based on the regularized singular value decomposition (RSVD) of the matrix obtained by reshaping the seasonal time series data. The method is flexible enough to capture two kinds of seasonality: the fixed seasonality that does not change over time and the time-varying seasonality that varies from one season to another. The new method is capable of capturing multiple seasonal patterns and how they change over time. By assuming the time-varying seasonal patterns change smoothly over time, the RSVD imposes a roughness penalty to effectively extract the time-varying seasonality. The proposed methods is applicable to the seasonal time series data with a stationary or difference stationary non-seasonal component. Our proposed RSVD approach is general enough to handle several irregular cases: (i) the existence of abrupt breaks in seasonality, (ii) seasonal time series with mixed frequencies, and (iii) the existence of multiple types of seasonality. Our proposed method compares favorably with the state-of-art X-13ARIMA-SEATS program on both simulated and real data examples. |
